B16 Weird idle and popping
i have a B16 obd1 in a 93 coupe and recently it will idle really low sometimes, under the 500 rpm range, and sometimes it will idle about 650-700. i do notice that before i get to stop the car will pop and backfire when letting off the gas at low speeds, lower rpms. i know to check the FITV and IAC and all that, but would one of those sensors make it pop sometimes? normally it does not pop at all. kinda weird and i have no CEL lights. any ideas?

You're either running rich or you've got a modified exhaust...
Running rich is more likely. When's the last tuneup you've had?

About 9 months ago, new plugs (ngk) new cap, rotor, and new nology plugs, didnt start until recently
plugs going bad already?
yes the exhaust is modified but, it was never like this before

running rich
i had the same problem with 2 of my b16 swaps. you might want to clean the intake/exhaust manifolds. check the plug gaps again.
EDIT: O, and low oil pressure can cause low/short idle problems. get an oil and filter change and powerflush your engine
