Well first off this is my first W-body and I love it. I have always had trans ams and this is a nice change for me. More room, more comfortable, better on gas, and it is still quick. Here is the rundown. I bought a 98 black GTP with 100000 miles. I bought it cheap because it has some minor issues. First off, the back windows will not go up and down by the switch, you can move them by hand. I pulled the door panels off and the cables are really loose. I read the how to on fixing the cables, is this the problem. I am used to track systems and motor arms not cables.
2nd problem, the sunroof is cocked up in the passenger rear. Pull the headliner and put it back on track?
3rd. The car starts and runs great, it just had the valve cover recall done before I bought it. Under moderate to heavy acceleration it misses bad, is it just the plugs and wires or is it a common problem on these cars? Some background on this, I spent about 10 minutes today trying to diagnose the problem. I pulled a spark plug and it was a Delco, looked like iridium and almost new, looks like new delco wires as well, checked the gap at .60. Is this right, do I have to run iridiums or can I run side gapped copper plugs like in my ls1 and if so what is the part number? Do I have to put those metal heat shields back on the plug wires?
Also the check engine light is not on and has not come on. While looking at it today, it looks like there is a bit of oil sitting on top of the manifold and it is wet around one of the injectors. You would think that if this was left over from the valve cover change(less than 1000 miles ago) it would have burned off, correct me if I am wrong or should I just pull the injector and change the oring? Could this be the problem?
Like I said guys I am new to this body and I hope Y'all can help out a rookie a little bit. Also I live in Denton(north of Dallas, TX) Anyone got any parts close to me or are there any local clubs
