- 5.7 hemi engine running rough and hesitating on acceleration. My gut instinct was to check the throttle body but it turned out to be something completely different. #hemi #ram #throttlebody #airchargesensor

****CHECK THE FUEL PUMP***
I just had this problem. I got the scanner and read the data nothing out of the ordinary. I did the sparkplugs, oil sensor , temp sensor thermostat and coil packs and started running Lucas even a higher grade fuel which minimized the hesitation and occasional no start. My MPGS dropped HARD I was getting 13mpg on a good day and 17 on the highway and hesitation at idle just slightly and would occasionally accelerate on its own. This went on for 2 1/2 years and I thought it was an electrical problem or tipm . For some time I even thought the torque converter was going to be the issue I even purchased it to install.
The fuel filter and regulator are integrated into the pump. Unfortunately I got stranded in Mexico and couldn’t get it to turn on a week ago. I towed it home replaced the pump and nothing else! My idle hesitations, self accelerations, rich smell from the exhaust , loss of power, and MDS rattle have all gone away. My MPG in the City is back to 20-25mpg. The truck runs like an actual hemi again and have my power on demand.
That was one of the first things I checked. My fuel system was fine. Glad you got yours fixed.
Sir Grease I had the same symptoms ... fallowed your tip ..runs great thanks man keep it up .
You are very welcome however this is something you might have to do every 1 or 2 years. I think I ended up doing mine three or four times. I'm glad it worked out for you!
Thanks for the video man. Have the same truck,225,000 miles. Running good. Always looking to figure things out.
You're very welcome my friend thanks for watching my video I really appreciate it.
Thank you for the Food heating Tip and the Air temp sensor Tip.
You are very welcome! Thanks for watching!
@@greasebellygarage I'm getting a bit of a shake when I am stopped ...you think it's the Air temp? And how to tell without buying one? I guess I could buy it try it on and if not return it!!
I love the intro 👌🏾
Thanks
Thank bro ,this tip helped me to fix the problem❤
You are welcome!
Great video. I replaced mine today, found out that who ever makes this sensor ran a batch with the thermister in it installed backwards. Apparently, these have to be installed in the right direction. It threw me for a loop when the p0013 code came back. Switched the wires to the sensor connector and it worked. Wondering how many bad sensors are out there or have been returned when a new sensor doesn’t do the trick because of this.
I'm glad you figured that out it's certainly disappointing at how low quality the parts are these days.
The mass air flow sensor is something I spray with mass air flow cleaner every 3 months. It helps reduce gas mileage.
That a great idea too. Thanks for watching
Microlon is great great product. I use it in all my engines
I'm going to have to look into that I think I've heard of it before. Thanks for the tip and thanks for watching my video.
So what direction should it be facing? It just spins in the rubber intake tube, is it inline or across so the air goes through the center across the blue part?
Shouldn't hurt anything to spin. But I would wrap some electrical tape around it and place the sensor with the broad part perpendicular to the air stream. Like a kite in the wind if that makes sense.
Did the electronic throttle body light come on and go into limp mode?
No I've never had that light come on but typically that means the throttle body is bad however I've seen bad throttle bodies without that light coming on as well.
Having same issue did you fixe?
I’ve had light come on and off right away the truck just started missing higher rpm I thought it was my gas but not so much now haven’t scanned it yet
I’m having the same problems you talk about, and I’ve cleaned the throttle body , changed the air intake censor, and changed the air filter and I’m still having the same problems. Any other ideas or things i should look at?
You may need new intake manifold gaskets I had to do that before as well.
I’ve been having the same problem and been throwing parts at is ( all new plugs, changed coil pack on cylinder 7 where the scanner says is a misfire, new fuel injector on that cylinder as well. Also put a new air filter in it, added some shudder fix to the trans since its tough to tell if it’s the engine or trans. I put a new camshaft position sensor in it yesterday and that also didn’t help.
don’t know what else to do but it’s getting worse. I posted a video on my channel a couple days ago showing what it doing but haven’t gotten any new suggestions on where to go with it next.
Note that it it pretty much idles no problem. Every once in a while I come to a red light and the idle will get a little rough for a second or two but it rarely happens.
@@HomeGrownPyro1did you find out mine has misfire on 4 I replaced all you stated still have
You may possibly have a failed lifter... Is your engine making any noises??
@@tavonrice1935 Unfortunately I have not had chance to look into it much lately…. I also bought a new car about 2 months ago and being that it’s winter here, I’ve put it on the back burner probably u til spring when it warms up.
My next step however, as someone suggested to me on another video, to take the valve covers off and have someone crank the engine over a couple times and watch the rocker arms and valves for any noticeable difference with any of the them compared to the rest. They said to look for a stuck valve, or one that is not moving as much as the other rockers. Once guy said he was having a similar issue and said when he was removing the valve covers he found a rocker arm just laying there on the bottom because the rocker bolt stripped out
I don't know how often you look at these, but I am looking at a 2010 2500 5.7 that bogs down after 50 mph. I know it needs exhaust manifold gaskets, but it's posted saying there is no O2 sensors, and no cats. They're blaming the missing cats for the Bog. Has new fuel pump, but wondering if its worth it. No Hemi Tick
That could certainly be the case I know these engines are pretty sensitive to the back pressure etc. get a price on a new catalytic converter first but I would probably take a chance on it if it were me
I have a 08 ram hemi. Has what i call a fluttering at road speed(35 to 60). Changed plugs, cleaned out throttle body to best i could. Changed valve below alternator ( name slips me). Sorry. Took for spin and still has the flutter. Unless i accelerate cant really notice then. And when parked i can fell just a slight flutter. Any ideas before I start throwing a fit. Thanks much
Oxygen sensors can do that without a check engine light. It's a pretty common problem and not very expensive. It could be several other things but I would start there.
EGR valve lol
Would the MAF cause this without check engine light. No codes are being shown
@@rtoo745 possibly but it can be cleaned. I would still just replace the O2 sensors anyway.
You know that's a possibility too I forgot about that one and it's a cheap repair
I hope this helps. Truck has been running funny for about a month now, at first i thought it was just an exhaust leak, then j started losing some pressure while accelerating at highway speed. Just now i went to get something to eat and when I backed into a parking spot it started misfiring like crazy. Came back to work and after i put it in Park i decided to let it rip and the engine shut off. Wtf???
You may have lifter failure....
Check this out from one of my shorts.....

Man I hope I don't. Truck only has 165,000 miles
I once found a diaper wipe stuck in my throttle there was no air filter
You don't see that everyday! Lol
Mine has it where it accelerates when braked randomly. & sometimes it has a choking when trying to turn on (SOMETIMES) It’s soo strange. I don’t know if it’s my fuel injectors that need to be changed or throttle. Also it still has the hemi tic even after lifters head gaskets have been changed. BTW NO CHECK ENGINE LIGHT appears! Man these rams… love em but ahhh really troublesome
Make sure your throttle body or air valve is clean and replace that temperature sensor like I did in the video and also make sure your battery terminals are good and tight. Sometimes they are faulty and they work themselves loose and they cause weird things to happen.
@@greasebellygarage I cleaned out my throttle body was really dirty & fuel injectors it’s been turning on now without wanting to choke! But it still accelerates when fully break or when I’m driving & im braking to go to go to a complete stop. I’ll be looking at my sensor. I didn’t check that. I’ll take a look tomorrow after work and get that changed! Btw mine also has that strange little knocking at times hopefully that goes away. Did yours go away?
@@William76850 acceleration during braking is a very strange problem. If you have floor mats, take them out and see if it does it. The only time my truck ever accelerated while breaking was when the all weather format got jammed on the gas pedal at a funny angle. The knocking noise on my truck never went away but it did get better with different brands of gas or if I put 93 in it it wouldn't knock at all. 7-Eleven gas made it knock like crazy for whatever reason. Check your floor mats and check your sensor and see what happens.
Ever figure this out? Mine feel like it wants to move while stopped. I think it could be my trans
Could you turn your volume up on your camera or however you filming like watching you but I'm better-looking hear you
I can change the volume in editing. Thanks for watching
What is the name of the sensor you replaced prior to the throttle body
It's an intake air temperature sensor
I have a 2012 charger rt ive replaced the fuel pump system o2 sensors and the car hesitates then fires up . And before all that ive replaced the intake air temperature sensor before all the other stuff so youre telling me if i change the air temperature sensor it will crank up without hesitation
I can't guarantee it but it certainly won't hurt and it's a pretty cheap part. Sometimes the hesitation can be defective fuel pumps or the check valve does not operate correctly. I actually went through that on my truck and had to replace a fuel pump 3 weeks after I put in a brand new one.
I had the fuel pumps put in the car a week ago from the dodge dealership for $1500 dollars so I know that's not bad what type of throttle body I need
I’m having a problem on my hemi 2019 only 9,000 miles sat for 2 years because of a side passenger accident, when I get to 40 Mph and I accelerate the idle is sluggish and it shakes a little when parked but beside that it’s not knocking. please help me!!!!
Check the basics first, coil packs, speak plugs, bad gas and possibly a bad fuel pump. Cars don't like to sit. Also make sure there's no damage you can't see like O2 sensor harnesses etc.
Thank you I will keep you update
Update my symptoms are now worst. It’s a rough idle and weird whistle noise at idle and accelerating so I’m convinced it’s the throttle body.
Update guys***** I had a bad rear drive shaft. The trick is running like a beast it has only 9800 miles now wish me luck
@@carlossanchez7096 I would have not guessed that. Glad it's fixed!
How did you yake the IAT sensor out and what iss thebpart numbet
It just pulls out of the air intake tube. I do not have a part number for it
@@greasebellygarage any special tool used. Reason why I ask my ram is hesitant on the gas and my per average on mileage has went down from 16is to 13 and 14 and goes down when im.om thr gas. Today I'm gonna change the air filter and see what that does and then maybe come the weekend tackle that sensor
@jimmywarden6320 there are no special tools for that sensor. It takes about 3 minutes to replace it. You should also check your throttle body and make sure that it's clean as well.
@@greasebellygarage well do sir thank you for the help
@jimmywarden6320 You were very welcome and thanks for watching. I really appreciate it. And by the way, have none of those things work. You might want to replace your oxygen sensors. There are four of them total. Sometimes they are out of spec and will not trip the check engine light. It's not unusual. I have to replace those at regular intervals. Good luck with it!
Would this work for a 2008 Chrysler Aspen 5.7?
Yes there may be some slight differences with your engine compared to mine but it should work.
@@greasebellygarage ok thank you....I ran a code reader on it lastnight and the codes were PO750 and PO118. It's hard for me to find parts here in north Dakota for my Aspen because they quit making and selling them long time ago.
Do the engine coolant sensor first. That's probably your main problem.
@@greasebellygarage ok I will try that, hopefully that fixes everything, but when I go to reverse, its shifts hard, like a good jerk, any ideas on what that might be?
I would try the coolant temperature sensor first and see if that helps you could also disconnect the battery for about an hour. Make sure your battery connections are clean and tight.
Stick it to the bottom of the hood.
What’s the sensor called?
Intake air temperature sensor.
@@greasebellygarageis that the same as a mass air flow sensor???
@@berardoferrari no
Jeez, you never said what sensor it was.. most trucks have more than one sensor.
I thought I did. It's called an intake air temperature sensor.
lol
