Bought an 89 k1500 350 tbi, and it threw a code 32 while driving home. Drove it around a couple times after and didn't give a code. Almost exactly like how my 88 Firebird with a 350 tbi acted. I had replaced both egr and solenoid on the firebird and it still did the problem. Then sold the car for double what i paid. So now I have this truck, and don't want to throw money at it just yet. It has headers, could those be causing an issue, and how do I get around that, change to a positive EGR? Going to check for vacuum leaks, too.

Also, it stalls randomly when going into gear or at a stop.

I got the stalling issue fixed. IAC needed to be reset. Can't find any vacuum leaks.

Going to drive it to work and see if another code 32 pops up.

Try cleaning the valve and the ports before throwing parts at it.

Stalling issue is not fixed, still does it, but only when in gear, shifting into gear, and/or turning from a stop. It does not stall if the truck is already moving. I have a sharp U-turn to get into our driveway and up a hill, and does that without stalling. But once I stop completly, and crank the wheel, or put it in D or R, it stalls. Doesn't stall all the time, but does it randomly, and at the worst times, too. Like once the light turns green, and I'm at a busy intersection. Cranks back over immediately.

Doesn't stall when engine is cold, stalls once it is warm. Bad O2 sensor? I've looked on other forums and that came up a few times. I have a used one from my GTA that worked before the header swap, going to try that.

Nice of this truck to have problems AFTER I buy it and bring it home... Laughing

Checked the timing...it's waaaaay off. Won't run at 0* base timing. Looks to be at about 20+* advanced. Timing chain?

Slipped balancer. Don't trust the marks.

Pulled the EST connector before playing with timing right?

You reset IAC, so it's a TPI? Did you reset the TPS afterwards?

EST was disconnected.

It's an 89 K1500. 350 TBI.

Yeah, I figured it probably slipped. Will have to have my dad time it by ear, he's been 100% right of all the times I've seen him do it.

Talked to a friend of my parents that's a mechanic, and given the symptoms, he said it had to be either the ignition module or pick-up coil.
