okay.. didnt want to hi-jac kthe other thread..
:thumbsup: i have had a huge exhaust leak for like 3 weeks before fixing it today.. now i get the p0174 code... i used my xcal to clear it and now i get the p1000 code.(havent driven it yet).
okay, what i can gather is after i fixed the huge leak (mac proC to stock E. manifold) is that my fuel trim/map? is screwed up and that maybe i should reset the whole computer.. all i got is the prochambers w/mil-eleminators and fr500 exhaust, jlt rai, i already cleaned the IAC before fixing the leak..now it ran fine after fixing the leak, before clearing the code. and now im thinking i should reset the comp... and no i dont have a tune on the xcal yet.
btw do i have to program the car before i can start using the xcal logging and other xcal programs?.. i bought it from mustang tuning doesnt talk to my laptop either... :nonono:
