SR20 supa rich @ idle

[2.0-TURBOcoupe]

ok so i posted on here a while ago about a hella miss at 2500 rpm and a rich bouncing idle but i seem to have narrowed it down. at first i thought the timing was off so a reset it to 15 degrees BTDC and still no progress. now thats out of the way i was going to set the TPS but i cant seem to find the correct way to set it...i know:jerkit: but anyway, i was wondering if by any chance that my richness at idle could be caused by running the wrong plugs? i am running NGK BKR6E plugs. i know your supposed to run BKR7E's in the sr20's with under 300 horsepower. here is a list of my mods for reference:

redtop sr20det

Hybrid FMIC kit
Greddy Type-s BOV
JDM equal length manifold
300zx O2 sensor
Walbro 255 LPH fuel pump
MR 3in O2 housing
MR 3in downpipe
Apexi N1 3in catback
stock sr MAF
stock sr ECU
stock t25 turbo

i did the vacuum leak test with the car running and sprayed carb cleaner aroung various notorious vacuum leak areas and nothing. so if you guys could help i would appreciate it. im kind of a newb here so if i look like the forum idiot i apologize.:bowdown:

Faulty O2 sensor might cause you to run rich in low RPMs.

Good Luck!

i have the fsm but everything is working. people have told me that the 255 LPH is too much pressure for the stock regulator to hold so im gonna try an adjustable one
