I've got an 89 GMC with. 305 it's doing the same thing and I've changed a shit ton of parts but haven't done this. I promise if this works I'll cry in joy I just want my damn truck back and running
Same problem with mine man replaced the ignition control module brand new cap and rotor now i replaced the EGR control valve solenoid and I’ve got to replace the knock sensor and the EGR valve let me know if that worked i was getting code 42
I've always had an old 350 Chevy with a 650 double pumper Holley and a HEI distributor.... Runs perfect... Now I have this 350 TBI.... what a load of shit.... I rebuilt the engine. .. It idle perfectly... Had the problem before the engine was overhauled... when I want to accelerate... it is very sluggish and almost sounds like misfiring... Struggle to pass a Smart on the hi way... my 74 Camaro had more power... I replaced the injectors, overhauled the complete throtle body, replaced the EGR, EGR solinoid, MAP sensor, Idle jet, throtle position sensor, rotor, distribuler cap, plug leads, spark plugs, tempreture censor, electronic controle module... But still, no power.... must I replace the distributer as well? I am so sick of this TBI... Love my truck, but have the feeling to drive her as fast as she can run at this moment into a wall!!!!
Hey I have the problem with my 89 Chevy same set up as yours I put the new distributor in and the air module new fuel pump and map sentser. Well you can hear file pump kick on go down road about a mile them it shuts down what do u think boss thanks and have a good day
I got a 1990 chevy C /K 1500 and it stutters, stall and idle high and idle low and dies right when I wanna take off, especially in reverse. It's 9:30 pm but I'm gonna go check it out right now...... been working on it all afternoon. Replaced the fuel pump, checked the fuel pump relay, all good. It will start, run rough, but run, till you stop and want to go again, then the sucker stall, dies and won't start again, only after you wait a while..... Let's hope this solve the problem
No, ended up replacing the fuel pump and ignition coil and still wouldn't run. Checked everything else. Last thing I was gonna check is the fuel regulator, but It's my bosses truck, so he said, let's take it to a proper mechanic...... After 2 weeks, the "proper mechanic" couldn't fix it, he messed with it for a third week and then we went and got it. The mechanic said he replaced the spark plugs twice (probably had put the wrong kind in the first time) It runs ok, but we will see if the problem returns.... will keep you updated.
Oh and that idle air control valve, I took it out, looks ok, ish , was gonna get a new one for it as well.... That and the fuel regulator will be replaced if the problem returns
You would hear a hissing sound sometimes slight sometimes loud.. one tip if you smoke blow the smoke near the areas of your vacuum lines if it sucks in the smoke you’ve got a vacuum leak
So you went with a factory distributor. Thats an ac delco? Im having the same issues when hot. I have a 95 yukon with 5.7 tbi. Ive replaced everything you have replaced i used an excell distributor. Been blowing ignition control modjules like crazy and stalling when hot at stops. I just am curious if u used an ac delco distributor.
Were you having hard start issues as well? Mine takes literally 30’seconds of cranking (broken up of course) before she finally starts to catch. Then once she’s running, she stumbles a bit when I start accelerating, and then catches up and pulls.
Yes! Bad fuel pump. I didn’t think it could cause this kind of an issue, since tbi requires so little fuel pressure to run, but once I swapped it out, the truck fires right up.
I have a 1989 suburban 350 with a problem persisting for four or five years it will not restart in hot weather summertime 10 minutes it will not crank until it cools off summertime winter time never a problem I can go 20 times a day all day long and it never will not crank changed mostly everything fuel filter fuel pump carburetor motor distributor batteries cables starters relays map sensor coil another distributor every part I can imagine
@@user-zu7bs8jj4r got it running alot better with tune up , plugs ,wires cap etc . Now it only has torque convertor studder when lugged (under 55mph ) in o.d. Next im gonna clean out egr valve and ream out catalytic convertor.
I think you just saved me hundreds man mine does the exact same thing. Im gonna try to clean it tomorrow ad see what happens

Nothing works better than the stock ignition on these trucks so use the stock ignition even if you put a different engine in them.
Easy replacement but didnt fix same problem. Wasn't expensive.

@@johannlangner289 what about the cap and rotor?
Thanks for ur video
I thought it was a helpful video, thanks!
All good info, thanks.
When you changed the distributor did you replace it with another electric distributor or a vacuum advance distributor?
Did it sound like you had a big vaccum leak from the tbi?
What would it be if you hear that?
You would hear a hissing sound sometimes slight sometimes loud.. one tip if you smoke blow the smoke near the areas of your vacuum lines if it sucks in the smoke you’ve got a vacuum leak
@@evanharrington7341 can I be done be usin a blunt instead of a nasty cigarette
@@wildestcowboy2668 hahaha that’s what I use 🔥💪
@@wildestcowboy2668 you can also spray some carb cleaner near the lines to see if the idle increases from it

How about instead of pulling it out from behind your ear, you show us where you found that little guy.. Houdini
He did show it. back up and watch. Left side of TBI.
Were you having hard start issues as well? Mine takes literally 30’seconds of cranking (broken up of course) before she finally starts to catch. Then once she’s running, she stumbles a bit when I start accelerating, and then catches up and pulls.
Figure it out?
Yes! Bad fuel pump.

Lose the egr valve and she runs a lot better...

Stop firing the parts Cannon and take it to somebody who knows what they're looking at
Good lookinh
Would this work for low ideling?
Mine studders in o.d when steady on gas pedal, wonder if that could be the cause ?
Same thing with me,have you found the problem?
@@user-zu7bs8jj4r got it running alot better with tune up , plugs ,wires cap etc .
Now it only has torque convertor studder when lugged (under 55mph ) in o.d.
Next im gonna clean out egr valve and ream out catalytic convertor.
@@arkansastrey9694 did egr replacement help?
@@bitbinge cleaned out EGR and IAC.....still not totally resolved .
Next im gonna rebuild the throttle body, and bench clean injectors.
@@arkansastrey9694 well hey, if you remember me, please drop a reply with how it goes either way!
Where would I find that
je vais aseiller ce week end
Looks like my problem
Ralphie may?
😂
I don’t think I would count UA-cam videos as massive research.
haha wrong i built a 500hp track car from youtube
@@bullitt3275 bullshit...
@@bullitt3275 I would.
It's probably one of the best resources for most anything you wanna research so yeah I would have to disagree just a lot
Did you ever find out what it was sir?
The pickup in the distributor went out I bought a brand new distributor in the II valve and it ran really good for a long time
