got some codes, help!!!
So i noticed that my CEL light would come on and stay on when my ignition was on(with the car turned off) and since it was not doing it before i went and checked for codes with my jb4 and the following codes came up.
iam not sure if they're associated with each other and the one for low gas i am guilty as charged, the one that has me concerned is the misfire since my car does tend to idle crappy sometimes. Also as of lately i have felt like i have somewhat of a powerless at around 5,500rpm and up almost feeling sluggish. plugs were changed at some point last month and the hpfp has been replaced by the previous owner like 70k ago, i have an er charge pipe with a synapse bov and dci with jb4 running on map 5 as far as mods, any and all help or input would be appreciated. |

29F3 is a low pressure sensor that can go bad. If you have INPA, I would check the pressure reading on measurement block 6. There's a pressure value that should be around 5000 and fluctuate. If it's stuck at a higher value, that could be the issue.
Otherwise, could be any number of things. |

im sorry if the question is stupid but..what is INPA, is it like the jb4 interface? and when you say stuck around 5000, is that at idle or when running? and will this sensor cause any performance issues? and i would assume the misfire on cyl4 could be either an injector or coil since the spark plugs were already changed? thanks for the help |

INPA is diagnostic/info software that a lot of people run on their laptops. You need a special cable to use it and it plugs into the OBD connector. Look in the coding subforum for more info.
As for the low pressure sensor code, read more here: http://www.e90post.com/forums/showth...=286527&page=2 |
