Well, i hev resaerchered the topic and did not find anything new, so i figured i would try again. I installed a set of pacesetter shorties a few days ago. Since the install, my car has had a very bad idle, and a low rpm miss untill about 2000. I have a new coil, plugs, wires, fuel filter. It only happens when he car warms up, so i assume in closed loop. My guess is 02's or MAF. The car seems to be running rich, also gets poor gas milage 10-12 mpg. I have also cleaned my EGR and it is working properly. Any ideas before i get 02's?

 

make sure wires aren't grounding on primaries

 

My cable routing is kinda bad, the wires dont touch the headers, but do cross between themselves a few times.

 

id put my money on the wires as well. had the same problem. do you get an ses light when the car warms up? if so, get it scanned to know for sure what it is, although there again id bet its one (or both) of the o2's. hth

 

I'll try to move the wires when i get home today, if that doesnt work, im gonna go pick ip some new O2's.

 

Another vote for wires.
