Question about Mercury Cougar
Hi, the code that you are getting, p0306, indicates that you have an ignition miss on cylinder number six. This would likely be caused by either a bad spark plugs or ignition wires. From my experience working on these cars, it is best to replace both the wires and the spark plugs. I have done quite a few and I'm certain this will solve your problem. After 10 years of service, the ignition wires should really be replaced as just good maintenance anyway and the plugs are fairly cheap...just a little difficult to reach the back three. You'll need an assortment of extensions and a piece of hose to start the plugs down inside their holes. Once these items are replaced, you can reset the computer or just drive the car and it will eventually reset itself after the miss has been eliminated.
Just let me know if you need more info.

The engine and automatic transmission in this vehicles drive train are fully electronically controlled by a computer called the PCM and TCM (Power Train Control Module, Transmission Control Module). When a problem like this or other drive-ability related problems occurs the computer stores a record of the problem (there are of course some exceptions to this, like the fuel pump, engine coolant temperature sensor and MAF sensor for instance) in the form of a fault code in its memory, to read these fault codes you must have the systems memory scanned with a special tool. Once the fault code(s) are read you then must perform the appropriate diagnostic testing to find and resolve the problem(s) DO NOT REPLACE ANY PARTS UNTIL A TRAINED TECHNICAIN HAS DIAGNOSED THE PROBLEM TO AVOID SPENDING YOUR HARD EARNED MONEY ON PARTS THAT MAY NOT CORRECT THE PROBLEM
