Quick tip. If you ever have a rubber or plastic hose or pipe that you need to put a bend in, fill the tube with fine sand. Then, heat the rubber to melting point and bend. The sand will prevent the tube from kinking. Once cool, you have your shape and it stays round. Then just empty the sand.
A lot of people are quick to blame the opti spark for these symptoms but as long as you get a high quality one and the water pump doesn’t leak, it holds up really well.
Thats what I read a lot thats why I'm not jumping to the the opti. I ordered a new ac Delco coil pack and icm. Imma swap it out this weekend and give a update video.
Hey bro, been watching you for a while and love the content, if you have any questions on lt1 stuff let me know. Check your icm, if it’s not that, you can check the resistance at the opti harness and if they aren’t in spec it’s definitely the opti. I don’t remember what they should read but it’s on google.
Thanks bro I appreciate the input, im glad u mentioned the icm cus i ordered a new ac Delco icm and ignition coil off Amazon, it'll be here Saturday so I'll have a update this weekend on it. ✊🏾💯
Also try running a high mileage seafoam through the gas tank but make sure your exhaust system parts are clean enough to be doing this because if not it's going to run all that junk right through the catalytic converters and plug up the cats
i would try running Seafoam on a half tank of fuel til its almost empty, then change your plugs. At the very least you have clean(er) injectors and new plugs. Maybe holler at Jeremy at Faster Proms, he's got some good experience with gm LT engines.
Believe it or not one thing that does help with this issue I noticed in my 92 Roadmaster for the voltage fluctuation is you have to make sure that preheater hose is installed in the air intake going to the exhaust yeah it seems like such a stupid thing but that and yeah make sure you're running 93
Hey guy, check the idler air control. Mine was carboned up. I had the same issues. Did a video on my channel. Worked like a charm. Too many blame the opti or EGR and its the idler air control.
Also yeah EGR valve and the port going into the intake and new oxygen sensors. Also not a fan of the optispark system and general that motor has so many more things that can go wrong with it there's much less Parts in the two-barrel carburetor CBI
bring the window up, use duct tape and it will stay there ,you are going to need the very small C clamp to push those roller in ,vice grip might work but you don't have enough room and you get frustrated
that broken hose goes from purge canister solenoid to intake manifold, you can not find the elbow to intake anymore but you can use spark plug boot ,and it work perfectly as for the first hose, you can just block it off at throttle body and put small filter on top valve cover,(all it does suck the fume and sent to intake to burn! you really don't need that! P.C.V is on driver side right next to tiny vacuum hose coming from opti vent with one way check valve, which blue side should be facing towards intake manifold
After changing my icm,coil pack, broken vacuum lines it still did it. So I changed my optispark, plugs and wires and she ran like a dime. Start small and go big. I did the others first that way I wasn't changing my opti for no reason but now she run smooth again
@@350znissan350z id say change plugs and wires first. THEN go to the Opti. Cause in my case the wires were bad and creating a weak spark in the engine and all the plugs were fouled up. After I changed my plugs and wires it ran great
All 5.7's have voltage fluctuation issues sometimes they will go away and seem like it's fine and then I'll send boom it pops up comes back it's really not an issue and this is coming from somebody who is severely annoyed by this s***
@@EVERYTHANGDIESEL sorry I'm not familiar with the acronyms. But yeah a check engine light could mean anything in which I'm sure you already know. But from what you described the first thing I would do is check the air filter sensor and if that still works then I would go through and pull each spark plug make sure they don't have any buildup.
Man I have a 1995 caprice classic and it’s doin the exact same thing and I can’t figure it out but I am goin to replace the vacuum hoses and see what happens but did you ever exactly figure out the problem with it??? If you can get back to me that would be great!!! @EVERYTHANGDIESEL

For the 90 degree hose just use a spark plug boot. Cut off the boot and add a clamp to hold it together.

@@EVERYTHANGDIESEL would you be able to provide the part # for the hoses you bought? I needed a few but never did find the right ones.
I went to my local advance auto with the old hoses and they gave the those. I got 1 foot of each for the smaller line and 2 ft of the long line
@@EVERYTHANGDIESEL okay cool thanks man I appreciate it!
Might be a blocked fuel filter. Change the fuel filter. LT1 fuel filters block up every 10,000
Since replacing the hoses didn't completely the idling problem, did you ever figure it out? I'll be replacing the cracked hose tomorrow.
OMG. I've been fooling around with mine for a year. My hose was cracked too!
Good video man ! Start her up in the night when it is dark, and check if there a any sparks from bad wire.
I heard people say that imma give that a try!
I really miss The EVERYTHING DIESEL CONTENT!!!!!!!!!!!
Trying swaping out the fuel filter for a new one also I had 3 b.bodies 94-96 LT1 something it’s the little things
I got the new filter in the garage just gotta swap her out

Hi, did the icm resolve any issues?
Also try running a high mileage seafoam through the gas tank but make sure your exhaust system parts are clean enough to be doing this because if not it's going to run all that junk right through the catalytic converters and plug up the cats

I added a 1/3rd of seafoam to the tank haven't drove it enough so it can get cleaned up. But I know seafoam works from past experience

It could be fuel pump regulator my friend, ck. Vacume line to reg. If any gas backing up in line, need new reg. Same thing I had with my 95 z28 5.7lt1
Hit up auto zone or places like that to test the electrical system...why not, it's free
True that imma get the alternator tested
Use a spark plug boot for that vacuum line an old one.
Hey guy, check the idler air control. Mine was carboned up. I had the same issues. Did a video on my channel. Worked like a charm. Too many blame the opti or EGR and its the idler air control.
I will be looking into that as well. The car is running excellent after changing opti but I'm sure it could use a good cleaning.

What did the hesitation come from? Did you ever find the cause?
Ur pcv is on the driverside of the intake under the Throttle cable
Thanks man, I didn't know that
Have you changed that dirty filter
That one vacuume line would solve all your problems
bring the window up, use duct tape and it will stay there ,you are going to need the very small C clamp to push those roller in ,vice grip might work but you don't have enough room and you get frustrated
Thats exactly what I did except oi used a suction cup on the glass instead of tape to.hold it
did u get the issue fixed if so can u tell me what it was bro my car doing the same
Was it the coolant temperature sensor?
that broken hose goes from purge canister solenoid to intake manifold, you can not find the elbow to intake anymore
but you can use spark plug boot ,and it work perfectly
as for the first hose, you can just block it off at throttle body and put small filter on top valve cover,(all it does suck the fume and sent to intake to burn! you really don't need that!
P.C.V is on driver side right next to tiny vacuum hose coming from opti vent with one way check valve, which blue side should be facing towards intake manifold
bad spark plugs or wires, as its running spray water on the spark plug wires see if it stumbles..
Thank u, I will try that. Someone else told me about the icm I'm gonna be changing that and see if it helps
Lmao i had the same exact problem with the same exact lines
You ever figure out the stuttering issue? I'm having this problem
After changing my icm,coil pack, broken vacuum lines it still did it. So I changed my optispark, plugs and wires and she ran like a dime. Start small and go big. I did the others first that way I wasn't changing my opti for no reason but now she run smooth again
@@EVERYTHANGDIESEL u changed plugs and wires with opti?

I HAVE THIS SAME ISSUE HELPPPPPPP MEEEEEEEE
I switched to torqhead an my engine is still lacking power .. if I hit it , it stalls, but if I let it climb it’ll go … smh crazy
Misfire, I’d change the cat after a tuneup and ignition
26 year old cats probably time
Great video bro 👏👏👏
Thank u man
You need to get yourself a code reader it makes diagnosing a problem a hell of a lot easier.
I got one but I need to get a obd1 reader. I didn't have any cel though
@@EVERYTHANGDIESEL cel? Do you have one with out a monitor?
Check engine light* and I got a obd2 scanner that has a little screen
@@EVERYTHANGDIESEL sorry I'm not familiar with the acronyms.

Thanks for tips bro. I already cleaned the maf sensor and still did it. But once I change the icm I'll go from there
Toss some no2 @ it
Guaranteed run better
Brody it will be easier and more understands if you cut out all the extra talking.
what was the problem?
Bad opti. Changed, opti, plugs and wires and she runs like a dime.
Click bait
Get to the point
Stop talking so much n get to the point my guy
