Ok, I was at home all day and decided to go out and get something to eat. Drove my car about 3/4 mile to the gas station to get some gas and the car ran fine. Turned the car off to put gasoline in the tank then turned on the car and it started to idle and jump bad. Turned the car off and restarted it again and same thing. Then noticed my check engine light flashing off and on so I drove my car slowly to the Advanced Auto Parts store and had them run the OBDII test and it came back with "P305, cylinder misfire on 5".

Now, I just did a full tuneup which I had all new spark plugs and wires changed in January 2007 which is now about 7 months ago and I have put about 26,000 miles on the car since January. Could the #5 spark plug have gone bad that quick? or even the wire? I checked the wire and connection is fine.

Vehicle: 2000 Chevrolet Impala 3.8L\

Never mind. Hmm chevrolet forum with no quick help or answers.

Called my mechanic and he came over and told me it was my #2 coil pack. 2 screws to take off, bought a new one and 2 minutes to put back on and walla, my car runs and purrs like a baby again. No check engine light flashing and no codes showing.

 

howd he figure out #2 coil was bad when it showed #5 was acting up?

 

3 coil packs on a chevrolet impala. Each handles 2 spark plug wires. coil pack #2 handles 5 & 6 spark plug wires.
