Hey guys, nice to meet you all, i have an 06 stage 1 roush with procharger on it
Recently my alternator went out and after i replaced it with sr performance one i started to have issues explained below (not sure if these are related with alt swap tho).
Car runs dummy rich, 10.1 afr on wideband, smoke on startup and gas smell. Both front o2 throw codes and show 0.9 volts when at idle or when accelerating which indicates stupid rich condition. When i put the car in a limp mode by removing maf and starting it (failsafe tune) car rans normal (as it can in limp) and o2 shows 0.1-0.5 volts which is absolutely normal range and car doesnt run rich. That makes me think that o2 are actually working properly and something else makes the car dump so much gas. Also when you drive and stop at the light in neutral rpms drop to like 500 and go back up to 850
What you guys think it could be? Tune went to crap?
What i did so far:
-New plugs yesterday
-Cleaned maf
-Cleaned throttle body
Also car doesnt start normally, smokes crazy (gas) with gas smell and bogs down , in limp mode starts fine
