As the title says, My CA is leading out under WOT and sometimes at idle.
Car ran legit in November drove it home from the track. its sat for a bit. battery eventually died. got new battery, car idles fine, sometimes the afrs will be good at idle (14.4-7ish), or eventually lean out "---" on AEM uego. if i let it build revs slowly the afrs stay pretty consistent but, if i jab the throttle, it breaks up an stutters.
ARP rod bolts
s15 t28 (bought brand new)
car has ran great and been extremely reliable since summer 2015, especially since the last big drive i made in it, it ran fine until parked and sat for about 3 months. (Reg. is Exp.)
so far i have:
Drained the old gas out and replaced it
tested fuel pump and it checks out
getting good fuel pressure.
had 550cc injectors cleaned and flow tested, they're good
replaced fuel filter
checked for vac leaks and found none (except were half moon seals are, but ive had those leak even when running well).
drop resistor is good
injectors are getting 12v
spark plugs replaced and gapped at .28 (running 15psi)
ECU codes checked. their are none. (55) tested on 2 ecus.
pretty stumped at this point. ive just about triple checked all the fuel related things.
wiring harness is also fairly new. really weird that just started acting up all of a sudden. really hope its somthing stupid and small.
