First, P0135 - o2 sensor heater circuit (bank 1 sensor 1). Does this mean that the o2 sensor is bad? Could the cat be clogged? The SVS light has been on since the headers were installed, the car now has only 47k and is a 2000.

Next, the car is having a rough idle. Sitting at a red light, the RPMs will sit nicely at ~700 and then it starts waivering and jumps up to ~1000-1100 and goes back to 700. And during acceleration the car will heisitate. I origninaly thought that the problem was the bosch plat 2 plugs that I installed since this began shortly after they were installed. But, Friday night I installed new NGK TR55s and MSD wires. The problem is still there but seems to have died down a little. Maybe I gapped one wrong? What else could be making the car run like this? Could the o2 problem be related?

I'm not much of a mechanic, but I had a similar problem as you describe, and it was solved by replacing my TPS. But my car has nowhere near the work yours has had to it. Just an idea. I think it was like $26 for a new one. Good luck with the fix. Hope you can find it.

New TPS is only $26? Is it easy install?

It was quite easy, and I am pretty much not a car-fix it guy (although I am getting better). The one I bought was like $26 (I know it wasn't over 35, but I bought a couple things, and I may be confused). It was like a 10 minute install which really sprprised me.

Alright, I just got back from AutoZone.. I had the codes checked again to see if anything new has come up since the last time. Sure enough, I have codes p0134 and p0135. Can anyone explain more about p0134? I already know about the 135 code (, the 134 is new to me..
