Well I fixed MY problems with the V V T. After using the seafoam product and driving about 300 miles the CEL and VTC lights would go on and off. Yesterday, when I started the vehicle the lights were off and I made it to a dealer. I traded the car for a 2002 LX430 with 46K miles. Combining all the pending issues I was looking at I decided this was the best solution. VVT issues, power steering pump, tires, non working AC, inside trunk release switch bad and weak hood struts it was time to make a change. I was looking at investing $4000 in repairs on a ten year old car.
