Hey got a quick question. I changed my plugs because my car was missing and then drove it and it dident miss at all. Then I put my O/R H-pipe on drove it and dident miss any. Then I started it up yesterday and it misses like a mother. Almost all the time at woot and at low rpm. All the sparkplug wires are on and i cant see anything wrong. Do you think that it is a sparkplug wire burned out or something.

 

the next time you start it up, if its missing, take a screw driver or something and tap on the injectors. one of them could be plugging up and sticking. happens on the time on GM's

i wouldn't think it would be a plug wire, since you just changed them out. what brand wires did u get?

 

I dident change my wires, just my plugs. Sry for any confusion.

 

ah, well how old are the plug wires, how many miles on them?? and are they stock?

 

I dont know anything about them other than they were on it when I got it, and they are autolite 8mm Pro Series, they kinda look old, but I dont think it is them because it has a realy hard time at idle like it slows down to 450rpm then up a little then sometimes revs up to 1000rpm then slows agian. Kinda like the tps is bad but i just checked that and that looks good.

 

Please help me it's making me crazy!!!!!!!

 

what did you gap the plugs at?

 

I gaped them right in between the range under the hood, cant remember what but that cant be it.

 

why cant it

 

because it did it right before i changed the plugs that's why I changed them.
