I have a 1990 Acura integra that has recently been giving me problems starting. I have crank but wont start. I will come back 2 hours later and it will start just fine. When it starts it runs great! No idle issues, no lag, doesn't run rough. It has left me stranded several times now and it's driving me nuts because I can't figure it out. I have recently changed the fuel filter, new plugs, new starter, new battery. I'm thinking it might be the IACV but I'm not sure. Can someone please help!
