What chip and cat. conv.?

Code 44 is lean exhaust indicated.

Make sure the chip matches the injectors etc.

Car doesn't appear to be close to tuned properly. :frown:

Get yourself a TurboTweak emissions chip. Should get you thru.

Vacuum leaks, MAF reading low at light throttle, ex leaks pre O2, or clogged injector(s). Was the cat converter on there?
