hey, do any of y'all have issues getting your car to start when it's warm? like after a drive to the store, then starting it again 10 minutes later.Yes, the battery is corroded free and the starter has been rebuilt.

Might have something to do with the codes you had.

Check codes again. Check gas cap. This sounds like a vapor lock, but that is really rare in newer cars with fuel injection, etc. Crank position sensor, ignition module, mass air flow sensor, air idle control valve, or intake temperature sensors could be culprits. If you have had things apart, check connections and grounds. It is all about spark, air, fuel, and timing. Possibly a fuel pump or pressure regulator on its way out could cause a variety of problems that would mimick some of the problems you have had. If you have original airbox and mass air flow sensor, reinstall it.

i got the codes fixed except the vaccum leak. it's done this since we bought it.

Hondas had a faulty main power relay that would cause problems like that. Bad gas caps can let too much pressure build up. Try unscrewing it and trying to start. For a quick reference hot start trouble chart, check this out:http://www.vcoa.org/700-900-fa....html..."Possible causes of this situation include malfunctioning fuel pressure regulator, in tank pre-pump, slow responding Idle Air Control Valve, and to a lesser extent a faulty gas cap."....http://www.rockauto.com/catalo...NTIAC air idle control valve. They are pricey. Might want to clean it first along with the throttle body and see if it helps, if you have not yet.http://www.rockauto.com/catalo...NTIAC fuel pressure sensorhttp://www.rockauto.com/catalo...NTIAC, fuel pressure regulatorhttp://www.rockauto.com/catalo...NTIAC fuel pumphttp://www.rockauto.com/catalo...NTIAC fuel pump strainer

Echoing a lot of what has been said, I would check the starter signal circuit, the ISC valve circuit, fuel pump circuit, the crank position sensor, injectors, and the MAF and IAT sensor. Also, how old are your spark plugs and what type are you running?

the spark plugs were replaced last summer, replaced them with iridium tipped NKG or something like that.the mass air flow sensor is fine, i've replaced the PCV valve, i'll check the starter relay and stuff today.

replacing the intake manifold gaskets fixed the problem i was having. thanks for the suggestions guys!
