Whell, i finally got my car running decent, however not great.

When it gets hot, closed loop it eaither runs real rich untill the CE light comes on, then it runs real lean...using the wideband, and it really dosent have much power.

At wot it is getting a good 12.8 though.

I ended up replacing my MAF sensor and was wondering if anyone has any ideas

Im pulling code 334, egr valve position voltage higher than expected....i have that sensor held half way in.

Also, 176 and 177 which reads ;02 sensor rich and lean respectively, BANK 2....so any ideas?

WIth all the crazy stuff going on lately, im wondering if my computer is not correct.....any symptoms of a bad ecu?

Oh, and another crazy thing....over 5k it revs real slow untill 6,000 like its almost hitting a revlimiter.....im going crazy here
