car star fine when cold, it stall when hot, misfire
hello guys, let me give a little history.
What the car has: REVO stage 2+, Autotech HPFP, FMIC, KN Filter, Strait pipe, no Exhaust, strait out.
The symptoms: when is cold it star fine, idle is steady and smooth. but when it get to 85c normal operation temp. it start misfire and erratical idle. It will stall and it won't star again. let it cool for a wile and will star again. took it to the tune shop they install a new pump and rail pressure sensor but no luck. Vag don't give me no error code, I check parameters: coolant temp(85c - 87c) and fuel pressure(49.5 - 51.0 Psi).
Thanks!
