Could be a bad af sensor, or a vacuum line is disconnected

i double checked the vacuum lines, and everything seems alright, checked all of em right down to the wastegate and BOV. I figure the af sensor would throw a code if it were bad, theres always the chance that it wont i guess

maybe a bad connection to one of the injectors, maybe its not adding the right amount of fuel, maybe a bad injector, im just throwing ideas out there, did you upgrade your fuel pump?

maybe one of your injectors is grounded out??? Because the wires were black for both of mine and the is a pos and neg wire.. Someone in the past had similar issues checked his injectors wiring and one was backwards.. Try that!

yea I have a turbonetics kit with a GT3076R custom down pipe and vent to atmosphere wastgate on mine and I had the same problem it would lean so bad it would just flat line and my car had a supper jugging sound and what I did was did a boost leak test not sure if you know how to do it but its really simple go to a lowes or ace hardware or anyplace to get pvc piping and say if your coupler coming off your turbo is a 2in inner diameter coupler get a 2in outer diameter pvc cover one with a flat top and get a drill and drill a hole in the pvc cap that will fit a valve stem and make sure the coupler off the turbo outlet is very tight in the pvc cap and pressurize the system to confirm any leaks.. I did it the same way but instead of air I used a fog machine we use to find vacuum leaks… if you’re not sure what I mean I will email some pics of what I make!! and also if you take your + wire off your battery and your - negative wire off your battery and put them together you will drain the capacitors in your ecu and basically rest your computer and it will relearn and recognize everything.. That’s what I did now I have perfect idle never leaves 14.7 at idle witch is optimal air/fuel and when I hit WOT my a/f drops to 10.3-11.8... I found my bov o-ring was bad and after that it ran great also resetting the ecu… it possible could be your injectors that’s what I thought till I found a leak my naked eye couldn’t see….

damn sucks shoulda stuck with those other injectors..... but yeah wierd

well i checked out my downpipe and low and behold, theres an exhaust leak from the downpipe to spipe connection. until i get that resolved, i wont know for sure what the problem might be. if it goes away after i fix the leak, then mostlikely the leak was the issue.

Right know my issue is ive got the greddy down pipe which normally mates up with the stock spipe, but i had upgraded my spipe to 2.5 and it doesnt fit right. Any idea how i might go about fixing it? Do they sell a bigger doughnut to mate with the 2.5 spipe?

alright guys, it turned out to be an exhaust leak coming from my downpipe/spipe connection. I had recently upgraded my spipe to 2.5 and my down pipe was initially set up for a 2.25 or whatever the stock spipe size is. was able to get the leak taken care of, and my afrs are back to normal. i should be calling my tuner next week to set up an apt for the fic and injectors. wish my luck... going for 300+whp
