hi all,
been having some problems with me r33 gtst. On idle it wont hunt at all (revs stay about 1000rpm tho), but as im driving and put it into neutral to come to an intersection it starts bouncing between 400-1500rpm (sometimes stalling), it only does this after its had load applied to it. I've tried to search and found a thread or two but i did the things they said to do, but nothing helped,I've tried:
- spark plugs, all good, gapped at 0.8mm
- acc valve, was dirty and cleaned it out
- throttle body cleaned out
- spray contact cleaner on most connections
- borrow some1 elses afm, no difference
- checked for weird noises but nothing
- checked all hoses and pipes, for vacc leaks
- checked charcoal canister
- cleaned out BOV
- regrounded fuel pump (inside the boot)
mods on my car are:
Garrett gt2535, stock ecu with SAFC, full exhaust, blitz pod, cooler, turbotech b.c, sard FPR, catch can
got the car dynod at pretty much 200rwkw (which i thought it would be higher) and tuner couldn't find the problem as he ran out of time to find it.
could any1 with a similar problem help me out?? or even throw ideas at me so i can check it
also i might have forgotten some things i've tried so if i remember, i'll do an edit
