Hello I have a 88 iroc with 350 TBI. Did the 350 swap some time back an my fuel pump went so I replaced it still have this sputter.
Some times the car stalls when stoped. But starts right back up.
In the video you will see every thing on my cluster be out of wack it needs to be replaced.
Anyways I tried messing with timing new hotter plugs everything. Im lost.
Have a look at the video an maybe you can tell me.
I like to add that it was a cold start.

OK I messed with the timing some now I can drive with out stalling at lights but it still sputters an idle drops some then kicks back up. Kinda like I have a big cam in it .the cam that's in it is just a little bigger the stock. Also at high rpms it will stark knock.

Still stalling randomly at lights
Car has good power burns no oil. I can burn 1st an 2nd easy.

It seems it stalls at lights when its up to temp and the idle is normal.
Also when it stalls I have to let it set for a min or 2 because it won't start acts like its a weak battery I know its not. This could be a weak starter maybe.
Don't mind my cluster its bad.

Check your ignition control module, it's in the bottom of the distributor. It can be tested at your local parts store. I had a similar issue with my car.

If thats not it, let me know.
