Car Struggles to Start After 1-2 hour Off Period
My car starts perfectly fine and fast when its completely cold but after driving it and having it stopped for 1-2 hours (so engine is still warm), it struggles to start, takes like 3-5 seconds turning and I give a little gas too. It is a street ported engine, is that normal? Thanks. List of mods follow...
rebuilt engine with street port and 3mm apex seals
upgraded Bully clutch
Walbro 255lph fuel pump
dual filter K&N intake with heat sheild
3'' down pipe and 3'' cat back exhaust
Pettit ecu
H&R sport springs
Hawk hp plus brake pads
Apex-i turbo timer
Autometer boost gauge
Brand new tires 245/45/16
Brand new OEM rad 500km ago
Clarion head unit with 4 clarion speakers
Pivot headlight controller (sleepy eye look)
strut tower brace

Sometimes trouble with warm starts can be blamed on a low compression engine. Since your engine seems to have been rebuilt it could have been clearance improperly or just worn how housing and plates. If you have the tools handy give it a check and see if you can eliminate that option.

I've been having the EXACT same problem and I too have a street ported engine. Also if i let the RPMs drop too low, the car stalls from time to time. Does that happen to you too? I cant seem to figure out the problem.

My stock reman starts fine on a hot engine but the idle will hunt and it will sometimes stall from this. The idle usually goes back to normal after I take off and drive for a little while.

thewird, that vacuum (16 inches at 900 rpm) is fine for a ported motor. I would say you have a tuning issue, but with the pettit ecu that isn't really possible. It wouldn't hurt to swap out your plugs and wires, and possibly your coils. I've seen instances where the leading coil will crap out once it's hot.

If its just unscrewing something and putting in a new one I could do that but I don't even know where to look for any of those things mentioned. Of course I'm willing to learn because I'd like to do some things myself on my FD.

One last thing: I'm just making an educated guess. It may not be the coil......
