My car did exactly the same thing when I started my 3L for the first time with my chip... I checked everything for days and thought my engine was messed up until I decided to take out the chip...

Use your stock maf and stock ECU... In my case the Maf tables weren't the correct ones for the maf which I was using...

Hope it works out for you

EDIT: Just read the entire thread your problem seems to be different
