Ah so I ran the scanner, and pulled three codes, if anyone has any ideas on what to check, fix and what not, let me know. Note that O2 sensors are brand new...
KOEO...
542 Fuel pump secondary circuit failure control module to ground
KOER...
314 Air system inoperative during KOER bank 2
543 Fuel pump secondary circuit failure battery to control module

The first and last codes mean nothing, the EEC randomly throws those codes. The middle code could mean one of your O2 sensor isn't switching fast enough (old?), you have long tubes on, or you have some sort of problem with the smog pump system.

Interesting. Ok well there is one thing that I've touched on my exhaust system and that is the smog tube, which is disconnected and is free-flowing because I had too much trouble attatching it too my off-road H pipe and was told that with an off road pipe, it was not necessary to be attatched to it.

Well thats why you have that code then ![[Smile]](smile.gif) You're right, you don't need it with an off road pipe, but connecting that tube will keep your computer from giving an error code.

Ok sounds good, I'll probably find a way to connect it then next time I get the car up, but I don't understand how the compute would be able to tell that it is unplugged or how it would affect it, since either way it is free flowing into the environment? Also, for the last few weeks every once in a while my Check Engine light would blink on for a minute or so, usually during just a normal cruise rpm, then my idle would become poor (only at stop, if I was cruising in nuetral, the idle seems to be fine).
