I logged a file with HP Tuners and pulled spark plugs, and I came across my fuel issue. Bank 1 seems to be running richer than bank 2. Also, my o2 sensors S1 on both banks are not reading the same. They are way off. AIR has been removed and the rear O2's still need to be deleted. But what would cause this? Any help is appreciated. This is on an front mount turbo car. I have the in tank 255 pump w/ hot wire kit and stock injectors. The PCM did not throw a code for the 02's....car isn't running on all cylinders.

When you removed the air pump, did you plug the valves on the air pump tubes at the exhaust manifolds/headers? They can suck air & screw up the mixture.

Also you need to look at your fuel trims to see if they are very different side to side, this will tell you if there is a weak o2, or an air leak.

I have non egr manifolds. Also, I accidentally put one of the rear O2s up front. the O2 was pretty bad. I will be firing up the car again with the new plugs and sensor. Thanks for the reply Lonnie

Disconnect battery to reset computer for a few minutes before restarting. It will reset any learned fuel trims.

Will do.

Thanks again.
