OMG!!!! Major backfiring after header install
Re: OMG!!!! Major backfiring after header install You have to scan the pcm , The ses light flashes while it is popping? This is a misfire the pcm has just logged. This will help you chase it down much quicker.

Re: OMG!!!! Major backfiring after header install The clicking is either going to be air or electrical. If it's air, you might be sucking some in close to the O2 sensor, thereby giving you some real crazy running conditions. If it is electrical, which I think it might be, then it could be causing a misfire. Which brand of header? Also, check the wires between your body and headers on the passenger side. Sometimes they got caught up and fried. You might be grounding on the crankshaft position sensor harness. That will make the car run VERY badly, if it all. Hopefully it is something as simple as the plugs.
Re: OMG!!!! Major backfiring after header install Isn't the clicking sound consistent with AIR/EGR gasket leak? Check the two AIR and one EGR gaskets on your header for leaks.

Re: OMG!!!! Major backfiring after header install Changed all the plugs back to stock. (desperate)Checked the CPS, ok, checked the wires, ok. Then fired up the car and let it idle. That's when I heard the clicking noise again. Sounded like something grounding out. Turned off all the lights in garage with the car still running, and found the F****** dipstick was bent, contacting a coil pack, and grounding it out. Holy S***, F****** finally!! Was able to see the spark in the darkness. Thanks for the help guys!!!!!!!!!

Re: OMG!!!! Major backfiring after header install Great to hear you got it running good now but I'm a little confused, I thought you said the clicking sound was on the drivers side, isn't the dipstick on the passengers side?

Re: OMG!!!! Major backfiring after header install Yes, it is on the passenger side, but when under the car for some reason it sounded like the drivers side, but I never could pinpoint it. I still have a little AIR valve ticking, but who cares, since I can actually drive the car now. <img border="0" alt="[Fluffy]" title="" src="graemlins/fluffy.gif" />
