Map sensor problem?

[bajansuperman]

would a bad map sensor cause these problem, hard starting (taking a while too start) , over fueling, low vacuum,low idle, staling and misfireing at high rpms

Yes yes yes yes yes and yes.

thanks

ah, a fellow bajan

last time i had a bad map sensor, the car refused to boost properly, would start missing/hesitating as soon as boost came on

did you try a diagnostic? code 34 i think it was

you can also check tps, knock sensor, o2 sensor

[bajansuperman]

think it was 31 and 35 some where in that range would have to take a look again and o2 senso4 removed usein wide band

[gorganl2000]

are you using the stock ecu?---removing the stock o2 sensor will cause the stock ecu to run rich

yeah, check your map sensor and both the electrical and vacuum hose connection to it

maybe try a friend's map sensor and see if it cures the problem

[bajansuperman]

most of what is being said in that link is happening plus the car's not starting and i'm running a bigger turbo so running a little rich is a plus for me till in get the money to put in my management..........also i having the same chatter he's getting but from the compressor houseing would the same map sensor problem cause this

[gorganl2000]

chatter normally associated with not using a BOV or using Mesh or a short intake to turbo

i'd strongly recommend you check the Map sensor and Tps setting

plug back in the o2 sensor if you have it disconnected, as the car will run like crap without it-----same goes for the knock sensor

[bajansuperman]

ok fix couple thing but still not starting and gettin code 51

[mikey4410]

Just so u are aware dude a map sensor failing is seriously rare.almost never happens,plus ure code error isnt map I know that.of he top of me head maywell be a tps issue

[brendonware]

I have error code 31 which is making it not start, but its fine once its started "right" as sometimes it starts giving me a really rough idle and smelling really rich! no idea what to do! lol
