Car has some hesitation/miss when accelerating through gears but runs fine at highway speeds or even slower cruise speeds. Mileage is below 30 per gallon. I have replaced fuel filter, air filter, egr valve, distributor cap, rotor, plugs and wires. Also ran injector cleaner into gas tank. My local mechanic came up with the following. Check engine light doesn't light upon starting the car and is not on when running. A diagnostic check for timing retard results in advancing the timing.
have the same problem?
