purchased a 1997 vw passat vr6, car will start cold but after up to operating temperature and shutting down car, it will not restart till engine is cold. Scanned car and got these codes, P0118 engine coolant temp circuit high input, P0103 maf sensor high circuit input, p0113 IAT sensor cicuit high input, P1580. Bought this car used, 2 oxygen sensors where disconnected, bought new ones and installed, ordered engine coolant sensor and temp sensor but did not come in, what could be causing this, really need to be able to run this car since my other car is dying and really loved my previous 94 vw.
