There are no codes for valve or timing unless you have low compression which wold give you the misfire code. The only tsb on your car for a misfire code is an aftermarket installed alarm system that will destroy your converter and cause misfires because it'snot circuit borad driven and shuts the fuel on and off and shold be put to starting system. As far as timing the belt shold be replaced as a kit at 60k unless in California then 105k. Normally akit is used so water pump pulleys, tensioner all get replaced at same time. This is an interference engine so if the belt breaks or slips your valves bend. They also have aproblem with crank sensors which are in the timing cover so if they aren't plugged in right they screw up but I don't think that is your problem.
