Car has no power and shakes Just got done with my pacesetter install and as far as I know there are no leaks. However, in driving the car home it has absolutely no power, especially in the midrange and it starts to shake. It does not accelerate very smooth. Does the computer need to readjust or do I have some other kind of problem going on?

Check your 02s, mine did the same thing and ended up being one of the 02 plugs was resting against my header and melted and the metal in the plug was touching and reaking havoc on my computer.

Car has never driven fine since I have installed the headers, when its parked and I rev it it's fine. But when it's under load it bogs, sometimes bucks, and is just down on power in general. Im also throwing codes as well.

I'm going with the plug/ plug wires. When my brother installed his last month his was doing the exact same thing. I looked in the bay and saw the plug wire not fully plugged in. You have to push it kinda hard for that second click.
I vote for the O2s. Check codes. Especially if as you say at initial idle /start up it seems fine- Meaning the O2s are not online yet and you are still in the open loop fuel tuning. I have had these symptoms /situation before and it was one of the "front," O2s- they do the fuel- Short of having a code reader at your disposal wait until the car is cool and swap the front sensors to the back-one side at a time
Sounds like what mine did to a T. Under no load it seems to run fine but as soon as you try and move it "chug chug chug chug chug" I would bet money there is an exposed 02 wire somewhere.

Well, car did not make it to work today, stalled three times before I decided to take it home. Made an appointment with MORE Performance on friday. My rear O2's have simms, Maybe the front two are exposed. This may be a stupid question, but what am I looking for.
