Re: need help.
You need to scan or jumper a & b together on the connector under the steering wheel and see if any codes come up. How long has it been since the car has had a full tune up. Plugs, wires, cap and rotor, pcv, air filter, fuel filter, and O2 sensor. I may have missed something but you get the point. Is the MASS air flow sensor dirty or damaged? I know a tps sensor will go bad, but in all the years I've owned these cars, I have never had to replace one. I can also understand why the previous owner will not answer your calls. Once the car left his place it's really not his responsibilty any more. You never know when something may go wrong with a car. You can test drive it for 3 hours and all is fine. Then when you drive it home and something happens. That does not always mean the the previous owner new that was going to happen. Good luck.
