Default Help please

Keep getting two codes. Can't remember the numbers. But they say boost key on rationality,map sensor too high,long. Only happens when it's cold and I shut it off before it warms all the way up.

Thanks

yea, i actually got a ticket for leaving it running while i went into i store the other day. damn military police. he really didn't like it when i explained to him that his job is all about screwing other soldiers over.

that to the side. if anyone has any insight into this issue i'd be very grateful.

I've done the map sensor and checked my boost fooler. It's still lighting up. Thanks for the input.
