ive read every idle issue thread there is. tried everything i can think to try. my car just wont idle… it doesnt even try to idle… just boggs and dies. when it does try to idle its very rough and only for a few seconds… here is everything i did. i did a fresh rebuild on my b18a1. arp main studs, rod bolts, and head studs. new pistons rings. all new vacuum lines, car ran flawless 5 months ago when i parked it. now it idles when cold. but after it warms up i have to give it gas or it stalls… it’s a 90 obd0, runnin obd1 injectors with a plug in place of resistor box. i accidently messed up the threads in spark plug hole on cylinder 3. but it wasnt so bad another spark plug wouldnt torque down to spec. cleaned everything top to bottom. iacv and fitv both have been cleaned. new plug wires and ngk plugs. no CEL’s. i drove it 50 miles no problems at all driving. almost sounds as if one cylinder is missing… ill post a video up tomorrow. any help would be very appreciative.
