*Check Engine* Under Boost

Whenever I boost above 2 psi, I get a check engine light? WTF is the cause of this? Bad boost sensor? Bad AFM? Anyone have any clues? Thanks in advance.

I assume you have the factory ecu. I don't see any stand alone listed. Can you pull the code and list the errors?

I could do this, but I would need a thorough explanation on how to do this code pulling sequence. Thanks.

I don't know if it is the same problem. but my car was doing that last week also.... actually i reved and passed someone in stop and go traffic.... i actually redlined it (it was fun...) but then my check engine light went on and whenever i boost over 0 (bars?) the car will seem like it is stalling.... and it was like that until i stopped, turned off ignition and started again.

Is it the same problem? and whats wrong? Boost sensor? AFM? BIG vaccum leak?

go to http://www.iluvmyrx7.com/1989_factor...ice_manual.htm and grab the entire manual if it all possible. The section you need for this explaination is in the fuel and emissions section, under self-disagnostics i believe

I have an extremely slow connection. It's been about 5 min and the page hasn't loaded yet. My car doesn't seem to lose power, maybe your'e fuel injectors are pushing to much fuel and you're bogging, I have no idea about that. Where is IceMark or nz_convertible?
