My Weekend Car Isn’t Running Right
Q. My 1995 Lexus SC400 (my weekend car) after sitting for a week and previously running perfectly, feels like it is running on two cylinders. My mechanic checked the catalytic converter and changed the ignition coil. This made a slight difference, but it still isn’t right. The mechanic advises that the problem may be a “jumped timing belt’’ but he is not sure. The dealership advised that if it is a timing belt problem the engine may have valve damage. Please help!
[fragment number=0]A. For a car to run properly it needs fuel, spark for ignition and proper engine compression. I would start with a recheck of the basics. This should include fuel volume and pressure tests, ignition system testing and engine/valve timing. There are two ignition coils in this model; the second coil could have also failed.
