Better to do that with a high end scan tool. You can't do it by disconnecting the battery overnight, but that can cause all sort of new problems. Where you say your speedometer 'sets' at 55mph, do you mean always stays at 55 even stopped, or do you mean if 'sits' at 55 even if you are doing 110?

The most likely cause of all this the VSS (vehicle speed sensor)

What is the error message? Also- if the disc is scratched badly, the laser in the CD player may not be able to read the disc. Try another clean CD to see if the disc is the problem.

This happened to mine a while back - run a cleaning disc thru it. The error pertains to the laser lens which is probably just dirty and can't read the disc. Good luck!

Mine wouldn't go off either -- service engine light wouldn't go off -- and the radio/CD player kept grinding. Just had the starter replaced, and everything is working fine now -- after 3 months of aggravation.

E20 : Focus Error Cause(s): The CD player cannot focus on the disc or there is an internal focus problem. Correction(s): Try cleaning the disc or using a new disc. Make sure the disc is loaded correctly. The road could be too rough or there is too much humidity. If the problem is not corrected, service the unit at an ACDelco Service Center.Information provided by http://www.carforums.net/showthread.php?t=11338

If this is a consistent symptom that occurs with all your cds....I would have to say the laser in the cd player is no longer working. You may try cleaning it, there are cd cleaners that are 15$ that u can try.but i think you'll find its out . sorry

error code 20The CD player cannot focus on the disc or there is an internal focus problem
you can try another disc
since you had an accident then my guess would be an internial problem
hope this helps

need a new radio u can find ones on ebay

you need a C-clamp to do it! use a 1" thick block of wood between the piston and the clamp and retract it back. if there are two pistons MAKE SURE BOTH OF THE PISTONS RETRACT AT THE SAME TIME. AND BE SURE THAT THEY DO NOT GO IN ON AN ANGLE.
