i got a check engine light and it was code 13 atmospheric pressure sensor. my car seemed to be running a little funny, kind of rich, and something very weird. when my revs would hit about 6-6500 rpms it would start to misfire like crazy as if it was sort of clogged or hitting my rev limiter. is this dangerous? and what can this be? i feel this is something with my fuel, like a clogged valve or it's losing some kind of pressure somewhere.

 

did oyu change any wiring. or anyhting. Usually caused by faulty wiring. Or bad ECU as whole. THE baro sensor is inside the ECU itself.

 

i got the exact same reading when i took my car around the block after i got my hondata tuned. it just went away. what have you done to the car?

 

no the only thing i have done is put a apexi afc and a msd btm thats it

 

guanranteed its you AFC you probably running the MAP on positive setting that way out of its reading range.

 

so what do i do please help me !!!!!!!!!!!!))))))))))))))

 

adjust your VAFC back to factory settings . disconnect battery or ecu fuse and be on your way.
