oh right, timing belt, water pump, tensioners, idlers.

dont forget trans and diff fluid. Thats only mechanical. You need to assess whether your suspension is still good or not.

Thank you so much. Not much of a mechanic...so will this cost me alot?

personally I would check your timing belt if it doesn't look bad leave it alone... if something isn't broke don't mess with it.. my car has the original timing belt and i have 180 plus thousand miles on my car....my spark plug wires are original and have low resistance still.

the motor isn't a interference motor so if the timing belt does break it will only leave you stranded

vaughn37

your talking big money if you let the dealer do them things.. thousands

Thank you once again.....Everything is running good except for spuddering when I excelerate. What's that all about?

The "spuddering" can be a number of different things. Have you done anything to the car yet, other then the oil change? The spuddering is either fuel or ignition related so the most common parts to change would be fuel filter, spark plugs, spark plug wires, distributor caps and rotors (2), and ECT (Engine Coolant Temp sensor) That's the common "tune-up". Changing the timing belt will not make your car run any better unless it jumped time. If it jumped, the car would be running really rough like a bad skip.
You say "Not much of a mechanic...so will this cost me alot". Cost will determine on how much of this you can do yourself. http://www.lexls.com/tutorials/ has the tutorials you need to do most of the work. If you can twist a wrench, get dirty, and follow directions then you'll save a bundle of cash. If you can't then the shop will wack you on the labor charges and raise the price on parts. (They need to make money too) How much of a mechanic are you?

Ditto on Deanshark and if you go through that stuff and still have sputtering, you should check the fuel pumps and the fuel tank. I have an older BMW 535 that recently had a sputtering issue and it turned out to be a rusty tank from gas having sat in it for 10 years. I had to wind up replacing the tank and the fuel filter

Having older cars like these is only cost effective if you can do some of the work yourself.
