No engine light but engine surges, sensor replaced and did not help. What is wrong?

Asked by Jan 01, 2007 at 06:05 PM about the Toyota Camry

Question type: Maintenance & Repair

Dealer does not know what is wrong. They replaced a sensor and tweaked the engine but the engine surges, (lunges) after it has been running for longer than a half hour at any speed generally at high speeds. When I release the gas pedal it stops but will surge again. Any ideas what is wrong?

you might have foul spark plug - check your spark slugs and if you see oil on the spark plug you have to change your valve cover gasket - thats what might be causing the problem .....
