Re: Please help Auto vs Manuel

Ok, the supra im looking at is burning a little rich. The mechanic said it could be a few things> either the mass air flow sensor on the intake itself, the Throttle positioning sensor, or one or both the O2 sensors. When I drive the car I feel a slight jerking motion in the higher rpm's, also it idles slightly rough. Have you ever heard heard of a problem like this with this year or engine. The engine is an attarco engine. It passed smog (in california) below the averages. Except it burns a little rich, do to the air flow reading problem. Any info would help
