Thanks!

 

So the code 35 is back for good while driving, not on and off. My iac connector wire has 4 prongs. 2 of the plastic prongs are broke but the metal conductors aren't bent or anything. Could this be a culprit as well. Before the code 35 everything was fine with the connector so I highly doubt it's it. Any input helps tho

 

What were your engine symptoms when your iac was bad?

 

Ok so I haven't got to the new iac yet but I will soon. I changed my knock sensors because of a code 43. Went away for a week and now the code is back. What could cause this? Also do you know an idle relearn procedure that I should do or does that happen under normal driving conditions. I cant help but think my computer may have something to do with this but please correct me if I'm wrong

 

Thanks for the help. I gave in and took it to the shop. Had 2 bad spark plug wires causing multiple misfires. i fixed the problem. Drives so much better. No more bouncing idle. We will see if all the codes stay off tho

 

my 94 gmc is the same way but it doesnt struggle to stay running
