SOURCE: Failed AZ emmisions test
On the side of the dome shape intake manifold closest to the belts, there is either a sensor with a 3 wire plug going to it or just a vacuum hose (it depends on what engine you have in your car as some have the valve visible while others have it hidden). If you have the dome, remove it and you'll see something that looks like a lid. take the lid off and the pcv valve will be behind the lid

You must have an ignition distributor to be able to reset or change the engine timing. If you do have a coil pack then the engine timing is completely controlled by the computer and there is no timing adjustment.

hi to find this, locate the top hose on your radiator, follow that back to the engine/motor, there you will find a small housing, inside that will be your thermostat hope this helps thanks

Since your cat was replaced you should be looking at fuel problems...even gas cap seal....check fuel pressure,fuel regulator,and evap system.>canister or purge solinoid,o2 senser...high nox is caused by the cat or fuel problems on these engines...high pressure in the combustion chamber...lean condition>air leak on hoses,or high compression caused by carbon build up ...there is no EGR on this car so don't waste time looking for it...hope this points you to your problem
