*note if you dont have anything relevant to say dont post*
So I installed the greddy turbo/perrin fuel rail/ tC 370 cc injectors/ straight 2.5 inch pipe with no cat into my rsr can. First time on the dyno blew up my stock clutch i was expecting that replaced it with a 6 puck. thats the background info so heres the deal. Today i was driving to work everything was fine its not a far drive my car started to stumble so i look at the wideband and at idle im running pretty damn rich like 13.0-15.5 now that was at idle so i continue to drive and when i accelerate it leans out hardcore to where the aem goes offline at 17.0 afr and when i let go off the gas pedal it goes rich probably lower than 10.0 afr now this isnt like im drag racing on the street just driving to get the damn car out of the road. The car throws a CEL/VSC/TRAC OFF then bogs down till it dies. I understand this could be a tuning issue but when i had it out on the dyno i corrected for the larger injectors and pretty much did a basic tune with the emanage till the stock clutch went. Never did finish it to get it perfect. But im trying to fiquire out how its possible for it to have gotten to where it is right now. is it because of the ecu? or im wondering if there is a problem with my maf. anyone got some info they'd like to share.

 

If everything was fine and then all of a sudden one day your tune goes to crap like that... I would recommend checking all your vacuum lines. A popped line could cause your A/F to freak out. Are you getting an eratic idle as well? It sounds to me like a line popped somewhere..... Tunes just dont disappear.
