kindafast - if you're running a lot of boost, you can throw MAP-related CEL's due to overboost in excess of what the car expects to see. IIRC, the 185mm crank pulley cars tend to eventually throw a MAP overboost CEL when tracking the car - AFAIK, it can just be cleared w/o any detrimental effects.

Is your intercooler leaking yet? You may have a bunch of crap caked onto it by now if that the issue. The AIT sensor should go next if that is the case, followed by an automatic trans 1.6l Honda Civic motor now under the hood feeling. Yup im in that boat. sucks a$$.

...sometimes too much oil from the filters can throw MAP sensor codes
Nonetheless, our MAP (004 153 72 28) and IAT (006 153 80 28) sensors are relatively inexpensive bits to replace when their useful service life has expired.

Hi and thanks for the replies!
Yes, I changed air filters recently.
I replaced the intercooler myself so I think I might of gotten a sensor or something dirty because after I replaced it car was running low 14's.
I am not ready to put a cross on this car, but I also don't want to spend thousands at MB for them to fix a problem they can't even diagnose. What they do is recommend to replace things that they think are wrong and from experience they always miss the first two parts.
