trying to narrow down my problems but cant keep the car running long enough to get it figured out. i change plugs and take the car up the road and they are fouled out in no time. i took the 32#'s out today and put a stock regulator back on. imma change the plugs tomorrow or monday. gonna put in some ngk tr55's. possibly gonna back the fuel back down with the tunercat if i can find the stock files. ive gotten a low map code a few times and ive changed map sensors and still nothing. i put bosch o2's in and imma change them back out to the delco's. i still have the stock fuel pump for now cause im trying to get the bugs worked out before i put a bigger one in. not for sure yet but it appears that the headers might have burned some of the wires on the passenger side fender that are wrapped in the foil. could they be part of the problem too? any info is greatly appreciated

 

Definately check those wires wrapped oin foil. I had a problem with one of my wires with a protective boot on it. The boot never burned but the wire was completely toast inside the boot. I had to take the wire off and remove the boot and saw the problem. You may have to re-route your wires so they aren't touching the headers.

 

ok thank you

 

Those are O2 wires and I think and ECM ground in there. FIx those wires first.

thanks dude. that might be my problem right there. my o2's are operating around 200-450mv causing it to dump a whole lot of gas. so im guessing that could be one of the problems right there. only thing is ill have to find a way to reroute them and repair the bad ones if any. i sure hope this is my problem cause i havent really gotten to drive my car much in 2 years!!

 

I put mine in that adhesive heat shield, that will make it stiff, then I tie wrapped them to the steel heater lines and then to the motor mount. Mine have been fine.

Only one O2 should be affected by those wires being burned, the right one.

ok thanks...guess ill have to get my nerve up to take that header back out tomorrow lol. oh well it aint doing me any good sitting there going to waste i just hope that fixes my problem

 

well after i unbolted the header and couldnt get it out i got under the car and figured out i could have just unplugged/unhooked all the wires and just pulled em up lol. but oh well. after inspecting them there are several of them with the plastic burned off of em. so after i figure out what the heck to do imma try to fix them and let that be my starting point. then ditch the bosch oxygen sensor and get some ac delco ones
then get rid of the nitrous plugs and get some stock heat range plugs and go from there. any tips or pointers will be appreciated
