I just put some hooker LT's on my 96 LT1, and i didn't buy the LT's with the egr and air pump option. i just put them on and my car doesn't run too good. MY car is throwing P0100 and P0400 codes. What is this??? MY EGR and air pump are not hooked up does this have any affect. Is there any way that i can bypass them or something so this will not happen? ANY help is appreciated Thanks!!!

I recently took my car to HPE horse power engineering and they deleted my EGR code, so it doesn't throw it anymore, but my MAF code is still being thrown. P0100 I have borrowed my friends MAF and the code is still being thrown any help guys THX

Those are MAF and EGR codes.
Check your wiring if the fuse is still good. Methinks you've burned the wire bundle on the passenger side with your headers.

Ok thanks to the person that told me about the fuse in the relay box under the hood, i have fixed the problem with my reverse. The fuse that reads 'engine sensor' under the hood, inside the fuse relay box was burnt, i replaced it and now my P1657 code is there no more, but MAF is still being thrown, P0100. Yesterday i reset the computer by disconnecting the PCM fuses and my check engine light went away for the whole night, but when i started it this morning, that ORANGE light stared me in the face!!! I pulled out the PCM fuses and the light did not go away any help guys???

Pull that damn light bulb out from behind the dash.
Show that damn light who's boss.

P0134 is your front drivers side O2. P0300 is random misfire. Check the wires on the drivers side O2 and make sure they're not burned or anything, then change the sensor. What cam do you have in this motor? I don't remember if it had a cam or not in it. If it does, that's why it's throwing the random misfire code. It's very common with cammed cars.

I personally don't worry about the codes if it's running ok. I've had my scanned once and I never solved any problems with that. Since then, I just don't worry about it.

After heavy modding the engin light being on is just somthing you will get use to. Im so use to seeing mine on that if it goes out , it would bother me...
