Alright here's my specs...
Smallport 4AGE in an E7 Corolla, engine is EFI, running a cut and shut smallport intake manifold with a blocked off cold start and it's completely stock.
Here's my problem, it's hard to start firstly but I attribute this to the blocked off cold start valve, basically you start it and unless you keep he revs over 2 grand it'll just stall, it takes a little over 5 minutes for it to idle normally but I usually just get it out of my driveway and once I'm driving it's fine.
Anyway most of the time the engine runs perfectly fine, healthy power, doesn't stall, no hesitation but randomly at anytime the engine will just start stalling, so for example you're coming up to a red light and you engage the clutch to change from 3rd to 2nd, the car will stall unless you give it some throttle in between changes but it will restart once you disengage the clutch (like a roll start), 2nd to 1st car will stall, disengage clutch car will fire up again, you can't sit at the lights idling either it'll just stall.
Also randomly and at anytime I'll return to the car after an hour or so of doing whatever and it just won't start, takes ages and heaps of cranking to get it fired up, sometimes it won't even fire up at all, had to get a tow last week.
I've had two Toyota, electric and generally all-round good people with engines check it over and they've been stumped. Sometimes it's perfectly fine other times it's not. Generally if I leave it for a few days it'll start up fine no worries.
I'm a patient kind of dude but this is really starting to piss me off, I'm contemplating just giving up on it all together, no one can diagnose the problem and these guys are pretty fucking good with engines, especially Toyotas. So does anyone have any idea what it could be?
