Just had headers put on the car a few weeks ago, and I'm having some issues. A couple of the plug wires got burnt after the initial install and the shop went back and rerouted everything, but now it's showing the same symptoms again. The issue is that I drove down to Dallas for a training class, so I don't really have anywhere I can work on it myself. I've checked from the top and can't find any issues, so I'm going to need a shop to look at it from underneath and maybe put a scanner on it (I left my cable at home unfortunately) and pull the code from the SES light. Any suggestions on a reliable shop in the Dallas area? I'm staying right at DFW, and would be driving home 635 to 75N, north Dallas area would be best.

 

im over in te garland arear and could check your wires for you pretty easily...

 

That would be awesome, I should be done with class around 4 today (maybe earlier) if you are available after that, or around noon or after tomorrow. Shoot me directions and what times will work for you.
And a big thanks in advance!

 

Well, unless you've got a code reader I don't think it's going to make any difference. I just finished doing some troubleshooting, and the car runs fine when you first start it, and only starts running rough after it goes into closed loop. Once in closed loop it starts idling rough, running really rich, and sets an SES. So I really doubt it's a plug wire since I've checked them pretty good from the top and it doesn't run bad for the first coulple of minutes until closed loop.

 

Long tubes??? I bet you burned the wires to the pcm.

 

Not sure, I checked everything as well as I could and can't find any burnt wires (other than two that run to the AC compressor that are a slightly toasty, which I've moved out of the way). There are some wires in foil sheeting that run up the passenger fender right by the headers if that's what you're referring too, they could have gotten too hot although the foil cover is fine. I'm going to try unpluggin the 02 sensors so it'll run in open loop until I can get it home and pull the codes.

 

try Keith craft motorsports in plano. they are near 75 and george bush. 972-578-3550

 

The wires on the passenger fender must be extended & reroughted. Those wires run to your starter and knock sensor (in the oil pan). Look over all of your plug in sensors throughout the motor, They might have missed pluging one in?

I agree if the headers are long tubes. Burned up the O2 wires since it only happens in closed loop. Either that or they tried to splice the wires together instead of using extensions and didn't do a very good splice job.
