Checked the codes last night and this is the only current code I have:

10 PCM - P0141

Obviously it has to do with the PCM, but what is the code?

Background: I installed LG headers about 250-300 miles ago. I went ahead and installed MSD plus wires and NGK iridium plugs with out of box gap. At WOT in high RPM's I get rapid "popping." Is this knock or what? Also, I am currently not running cats, so I expected my car to have a slight gas odor to it, but sometimes after I've been in the car for a while I think I smell like a gas station....is this normal? Thanks for the help

This code is from heated oxygen sensor (HO2S) heater circuit bank 1 sensor 2.

I recently installed LG longtube headers as well. My check engine light came on and I had the check engine light removed with the LS! edit.

I still get the code after I cleared the code. I think this is because I do not have O2 sensers in.

I will keep checking as well.

I have the front O2 sensors and sims for the rear. I don't get a check engine light. Are you having this problem of "popping" during WOT? thats the real answer I'm after.....why it is doing this, and what can be done to fix it

I do have a bunch of History codes too. maybe these codes help someone give me an answer to my problem....

The car still pulls hard without problems, and sounds great, as long as I'm not 100% throttle. Is it even worth putting the stock plugs and wires back to see if this is my problem...I would think if it were this I would notice more of a problem, along with power loss, across the board and not just at WOT
