The problem is the ECU (89661-42xxx). It must be either replaced or repaired. Mine was sent to
and was repaired. Buying a new one was way too unafordable for me (alost $1500 ---USED, NOT EVEN NEW---).

2003 Toyota Rav4 has P0303, P0300, P0301 and P0174 check engine codes. I replaced spark plugs. Still running rough

Sounds like you may have a weak fuel pump.Check your fuel pressure and if its not within the specs that are required then replace the fuel pump and filter.

1994 toyota camry turns on for only a few seconds then won't start anymore until spark plugs dry from excessive gas. Timing, ECM,TPS, and injectors have been inspected and/or replacedc accordingly.

it could be that the fuel pressure regulator is faulty & needs replacing, if the fuel pressure is too high the engine may be getting too much fuel.....hope this helps.....cheers.
