Does it seem to have less power going up hills ? Compaired to flat surface driving . Possible plugged catalytic converter . Back pressure test the exhaust system . Videos on youtube showing how to do both test's . The one jack mentions also . Also hooking up a professional type scan tool an viewing engine sensor data , fuel trims , O2 sensor switching rate etc...

Hi Irwin, Your car should only need new sparkplugs. Be certain they are gapped propperly! Other than that,check the air filter. If you can't see light through it, replace. Be sure to go around, not just check in one spot. Check the brake fluid, if down top up and get a shop to check the brake pads. As the pads wear, the fluid level drops to compensate. Check the coolant level, belts, an hoses! Wash an wax! Done! Frankster016

It has a maintenance recomendation from the manufacturer for replacement of the spark-plugs at 100,000 miles. You don't list mileage or V6 or L4 cylinder. Make sure engine is cold because the cylinder heads are aluminum and can be damaged if plugs are removed hot or overtightened upon reassembly. Remove spark-plug wires and replace spark-plugs. Sometimes the wires break when you remove them and will require replacement. If you coat the inside of the wires where they connect with the plugs with dielectric grease it will help prevent the wires from breaking upon future disassembly.
SOURCE: what kind of tune up should i get
depending on the year model.. plugs and wires distribitor cap and rotor. air filter. and defently a fuel filter. the more often you change the fuel filter the longer that high dollar 300.00$ fuel pump plus labor. will live. hope this helps.

ok ac system has a pressure switch that stops the compressor when freon is too low. they actually say it is ok for mobile a/c systems to lose a half pound a year. most a/c systems run on under 2 pounds of freon. so after 3 or 4 years some systems will just quit working. you are at 8 to 9 years so i would recommend you find an independant shop that will top off your a/c and see if it works again. this should not cost more that 50 to 75 bucks. If you were here that is what i would charge. I am in columbus ohio just to let you know. hope this helps and thanks for using fixya

I'd probably do a compression test on this vehicle. 2.2L engine, my info says 185--225 psi. 100 psi min.
The lowest cylinder reading should be within 70% of the highest reading. If the compression is poor, I'm not saying it won't run, probably will, but, it won't run like new vehicle. There could be other issues?
