Lexus ES300 rough running - David O'Callaghan
The vehicle has 160k miles, I am experiencing poor starting, rough idle and less power when picking up speed. I have changed the Exhaust manifold oxygen sensor but the symptons persist. Could the problem be the tempreature sensor? I do not trust the local dealer who has a bad track record. I have never found a third party workshop manual for these cars.

Distibutor cap or plug leads broken down with age?

None fitted to the vehicle, there is a crank trigger for the ignition and individual coil's with each plug.richard turpin wrote:

Timing problem? How is the fuel consumption? What are the spark plugs like in colour?
