ManicMechanic Posted May 8, 2008 Report Share Posted May 8, 2008 ...Maybe you guys can give me some ideas on why it runs like crap after warm up. He put another 3.1 in it and wasn't able to get it to run right so he sold it to me... I fixed a pinched wire going to the knock sensor so no SES light (previously a code 43) anymore but under any load it runs on 4 cylinders. I am getting spark from all 3 coils, all 6 injectors are within range, compression is good. Mostly over 2000 RPMs it bucks and snorts like a rodeo bull. I figured I'd throw a new set of plugs and wires in it, I already put in a new o2 sensor, new coils, new ICM, new CPS, new computer. I do hear a very slight vacuum leak but that doesn't explain why it runs great until it warms up. Any ideas? Quote Link to comment Share on other sites More sharing options...

ManicMechanic Posted May 9, 2008 Author Report Share Posted May 9, 2008 I'll try a new set just to be on the safe side, there was an extra in the trunk but I have a new set for the van I never installed. Quote Link to comment Share on other sites More sharing options...

ManicMechanic Posted May 11, 2008 Author Report Share Posted May 11, 2008 Just left it open, not a big deal here in Texas unless you do it several times a year. Quote Link to comment Share on other sites More sharing options...
