2003 VVT off idle motor searches back and forth RPM, at about 1/4 throttle it cleans up. When car is cold ( below 150 temp.) runs fine.
Changed most parts multiple times ( got spares now )
- throttle sensor
- idle air valve
- crank sensor
- air flow sensor
- O2 sesors
- cam position sensor
- wiring harness
- ECU
- coil packs
- water temp sensor
- complete throttle body
- the VVT
- intake cam
- than changed motors
- no codes
Any help much appreciate it ( COTA around the corner and way behind )
