  • Q:

    I have a 2002 Ford Escort with a 2.0L. SOHC engine. My scanner shows that at idle the ignition timing is running at 24 degrees BTDC. I checked the cam belt timing marks and they are correct. I replaced the spark plugs and wires. I checked for vacuum leaks. It idles rough and there is quite a bit of knock in the engine. Above idle it smoothes out a great deal. I think it might be the knock sensor but the service manager at the local Ford dealership said he has never seen one go bad. Thanks, Jeff

      With out the presence of your vehicle we would not be able to properly diagnose it nor provide you with a 100% answer. We would suggest taking your vehicle to a certified mechanic for a proper diagnosis before buying and having parts installed that may not solve or be the problem.
