My 86 accord (Fuel Injected) has been stalling out whenever the engine warms up. when its cold it will run fine with no spiratic idle. ive replaced the idle air control valve/ fast idle air, ported vacuum switch, tune up with new wires, new alternator, belt, you name it, and i still cant seem to find the problem, it will idle around 300-700 rpm on average when it warms up and eventually stalls out. i think it might be a compression problem but what else could it possibly be?? it also has a slight oil leak and sputters making air sounds out the exhaust if that means anything relating to the issue.
