i know my problem could most likely be one of many things but i figured i’d ask u guys just incase anyone had this happen to them before?
had my safc2 tuned a couple weeks ago…car’s been running great…then outta no where last nite … it starts to idle roughly…nearly dying…and had a few hard starts too…it still drives fine though?
any ideas?? im thinking it must be some sort of vacuum leak…
thanks
check your maf, and for vaccum leaks like you said. and the connection for your safc. i remember this skyline that had this pos afc and it was wired like crap. sometimes it would run good and other not, you had to move around the wires to fix the problem.
check the safc connections and wiring, if those splice connectors are used(cant remember their name but u can tie into a wire w/o cutting or stripping it) they r crap and never coonnect right. And if ure maf elements are dirty the car would do that too, try carefully cleaning it wioth electrical contact cleaner. Had the same probelm and that ifxed it, but i dont have a safc. Hope that helps.
