Question:
I have a 1996 Toyota Camry V6 with 210,000 miles. I recently changed the timing belt, drive belts, water pump, transmission filter and fluids, and tuneup with new plugs and air filter.

I had no problem before the maintenance. A week later a check engine light came on and stayed on. I took it back to the mechanic who did the tuneup. He put it on the scanner.

From 0-1200 rpm no problems and above 1800 rpm there are no problems. Between 1200 and 1800 rpm it shows a problem with 1-3-5 cylinders.

My mechanic put another new set of plugs and now a new set of spark plug wires.

The engine doesn’t seem to be running rough, but the check engine light won’t go off. Any thoughts?

Answer:
Wayne: All I did was tell my son timing belt changed and check engine light on for 1-3-5 cylinders and he said the timing belt is off one tooth on the right bank. Take it back to your mechanic and get him to reset the timing belt. The check engine light won’t go off until you do and you are loosing some performance in the mean time. Good luck.
