im having a similiar problem, aswell. my idle will be at 1400 when i turn it on. but slowly drop to 750,then go up to like 900,975,1200, you get the point. im thinking TPS,Fuel pump, Main Fuel P.Relay, dont think its an leak, i have never seen a leak. your last resort i guess would be to pay $100 for an Acura Technician to take a look at it. which i might do aswell.
