Ok guys heres my prob, a few days ago my car threw a CEL light and then went away for a lil bit and then came back and now its solid, doesnt go away, so i pulled code and said it was the map sensor, i put a new one and still doing the same thing.

So i looked at all wiring and everything was good and connected. I have a safc2 and i used to have my idle at -22 and now i have to put it at -50 cause it will puff out black smoke like crazy, also when heading down the road it tempts to sputter at certain RPMS
its weird cause it wasnt doing this couple days before everything was fine.


I'm thinking it might be an o2 sensor what do u guys think? Maybe dirty? Any help appreciated,
Joel

 

does it backfire?

 

did you reset the ecu after you installed the new map sensor?

 

yea backfires and sputters, yes reset ecu after map sensor was installed, think its my o2

 

check your o2

 

The service manual suggests checking for vacuum leakage or blockage between the MAP sensor and the throttle body.
