I had a code 32, so I changed the EGR valve. I decided to change plugs while I was here.

I have a set of wires and Distrib. cap and rotor. I have not put them on yet due to the little screw on the back of the cap.

Anyways after I changed the EGR and plugs, I have a miss now!!! The car doesn't have the power it should for some reason. I checked all my vacuum lines and wires ans such. I replaced the TBI gasket as well. Anyone have an Idea?

 

Did you gap the plugs correctly? Did you cross any plug wires by chance? I would check plug gap and double check that you have the plug wires in the right order.

 

Yes, I checked everything. I changed the plugs one at a time, and put the wire back on before moving on to the next one. Do you think that one or two of the new sparks plugs is dead or bad?

The car warms up fine. If it idles for a little while its ok, but once its warm or it is put in drive it starts missing like crazy. Wierd huh? I bought a new set of Bosch plugs today, I will swap plugs tomorrow hopefully.

 

I would stick with plain olkd AC delco's. Bosch plugs are not a good match with our HEI systems. I had a set foul out in 2k miles and many others have reported similar results.

 

Yeah stick with AC Delco. I got the Rapid fire spark plug and i love them. does you dont need to gap at all. I had Bosh too in my car and it gave me problems and poor MPG... Good luck bro.

 

those aC delco rapid fires are great plugs.There a little pricey but you get what you pay for

 

Yeah they cost a little bit more but its well worth it. If your going to replace the plugs, then those are the ones to get. Dont have to touch them for another 100,000 miles.
