IDLE

1993 Honda Accord • 2.2L 4 cylinder FWD Manual • 203,000 miles

Car starts fine and revs to 1300 then slowly idles down to 7or 800 rpm like normal, except when in fact the whole slight "missing" at random through all cylinders the whole time, warms up clears up slightly then stays missing, give it gas and miss seems to disappear, idle down engine misses when close to idle then at idle miss is very noticeable. Has plenty of power (barks second gear lol) also when warm idle air control valve I am assuming randomly "honks" heard through intake, fans come on to cool engine honk immediately stops) fans shutoff, random honking comes back, and exhaust smells like unburnt fuel, and when I pump the brakes it idles up to about 1500 then immediately stumbles down, what I have done so far is replace the Iacv, adjusted the fiav back to specs, (plastic washer shaped but all the way down), replaced oxygen sensor, new plugs, new wires, new cap, new rotor, replaced distributor with a known good used one, and checked engine light codes through kick panel jump connector, no codes, I'm stumped please help me haha

Check fuel pressure with a gauge auto parts rent it and check for a vacuum leak hoses etc. Soft or cracked.
