Only have had the car a week or so. Its mpfi (I didn't do the work) and throwing code 10 and code 14 (iac and iat). I am wondering if these would cause me to bog at 90% or more throttle.

The a/f gauge goes super lean and when stopped and i got WOT it almost seems like a launch control set at like 1500 rpm (although its obviously not).

The car drives fine other than that, though (other than the high idle from the codes).

Any ideas?
