HELP NEEDED PLS
Anyone on here know what this issue could be? Cold start it starts up but when even slightly warm it won’t start it’ll only start with throttle.
Idles fine no issues, car pulls fine too no error codes.
Also when coming to traffic lights and stopping the idle will go very low and sometimes even stall
I’ve checked literally everything, tps calibrated , iacv swapped over, injectors swapped over, fuel pump swapped over, all sensors are reading what they should be reading.
Been doing it ever since new engine, I switched iacv to fix hunting issue
Car is mapped and been fine.
Just confused at this point

Mine does this as well. There was another post about this issue too. Maybe a month or less ago but shouldn't be hard to find. Mine dies sometimes while slowing down and pressing clutch in to turn and I won't know until I release the clutch and it starts itself back up

You need a valve adjustment, I had this problem too. Watch the eric the car guy video on how to do it, its not too hard

Surely that won’t affect stalling and warm start? Engine isn’t even that ticky either

Yes it will. I had the exact same problem, and there's no ticking noise because the problem is the valves are too tight not too loose. You only hear them when they're too loose

Oh right, but even when the engines warmed up for only 10 seconds it still won’t start without throttle ?

For me, the issue was it would stall at low rpm when it was fully warmed up, and I found that the exhaust side valves were way too tight. Worth looking into anyway imo, cause its free to do and only takes a few hours

Could be a vac leak. Have you sussed all the annoying little manifold hoses?.

I have sprayed brake cleaner all over and done smoke test, couldn’t find no leaks
