I have an 02 Ford Taurus SEL V6. It idles rough and the check engine light is on. It seems to be misfiring in cylinder 2. I replaced the plugs, wires and ignition coil and still the same. Checked for vaccum leak and nothing. I even checked injectors and they are good and even replaced the egr valve. Today as I was driving, I noticed the car loss power and dropped speed, going 45 and dropped to 30 and then the check engine light blinked about 10 times and then stayed back on.

Go to Autozone and have the computer scanned for code/s its a free service this is your starting point finding out what's going on within the engine management system

I have taken it to Autozone 4 times in the past month and a half. The P0302 is always the issue and I replaced everything I could think of except for the converter.

Did you check the no.2 cylinder compression if not do so-

Engine misfiring can be caused by worn or fouled spark plugs, a weak spark (weak coil, bad spark plug wire), loss of compression, vacuum leaks, anything that causes an unusually lean fuel mixture (lean misfire), an EGR valve that is stuck open, dirty fuel injectors, low fuel pressure, or even bad fuel.
