This part was installed on a '01 IS300 and worked great! I was having very strange and difficult to diagnose vibration issues. My car felt sluggish right from the start, had sporadic power loss, rough idle and even stalled at idle a few times without ever illuminating the check engine light or the flight path control light error. I've done a tune up with new spark plugs, coil packs, spark plug wires, cleaned the throttle body and even replaced the mass air flow sensor to no avail. I took a chance by replacing the oil control valve and it worked! Now the car drives better than ever and I feel like I can finally use the full power of the 2JZ. If your car is having mysterious problems with power loss and rough idling, try this part. It's worth it and it's a known issue with the 2JZ-GE engine. Installation was EASY! Remember to remove and clean the oil control valve filter when replacing this part.
