I have a 99 LX and the gas pedal assembly is wobbling all over the place even though the closet nut to it is tight.When I am able to get my head in there it looks like something is coming apart and pulling away from the firewall. Has anyone ever seen this problem?It looks like a difficult problem to fix.I just don't know what to take apart to get at it.There are 93,000 miles on this car so I was thinking I can't be the first one to ask about this. Help!
