Engine Mechanical problem
2001 Cadillac Seville V8 Front Wheel Drive Automatic 203000 miles
I have a scanner I bought from Autozone for about 120 bucks nothing speacial. My cadillacs check engine light went on and I scanned it. It read p306 so I figured it has to be with in the 6th cylinder. So I replaced the spark plugs, and the boots. The only thing I havent replaced was the coil packs cause their about 200 each. What is the chances that one of the prongs on the coil pack would go out, and not the other 3? Alfter I replaced everything and the check engine light was still on I went into the system on the dash board and scanned the cars computer with out using a scanner I guess the car has a built in computer scanner. When it scanned it read p0300 and p306. But then I plugged in my scanner and scanned it it just read p0306. Now I really dont know were to start. I have also had the throttle position sensor, and the maf sensor recently replaced. I really dont know were to start now. If the computer reads p0300 and p0306 does that mean that its just the 6th cylinder or does it mean it is other ones also cause thats the only cylinder code thats coming up for something wrong with it.
have the same problem?
