hey all, new to the site, first time posting a thread. I recently bought a 89 firebird, 2.8 v6 for my son. when we first got it the car ran pretty rough, a lot of hesitation. car leaked antifreeze into the passenger compartment. it seems like the car sat for a while. so far i replaced the heater core and did a full tune up. when replacing the cap and rotor I noticed that the distributor was pretty rusty, I cleaned it up as much as i could. car is running much better, but it seems like i'm getting a popping or misfire on acceleration. the ses goes off when driving, then comes on when put in park. I got code 13,23,32 what should i work on first. oh yeah i also found that one of the fuel injector wire harness had been fried, so I replaced that too. I'm sure the #2 cylinder wasn't firing for a while, any suggestions would be awesome.

 

I'd start with code 13&32 which is an EGR code and O2.

 

New O2 and clean up the EGR or block it off if you can. That should help the car run better.

 

thanks for the feedback. I found a vacuum hose disconected that seems to feed into the egr.

 

The inside of my distributor was very corroded aswell. There's a little seal that goes bad, it's not much work to change, just time consuming..
