have had this code for quite sometime, car is undriveable, stalls 10-15 times on short trips, no stalling on long hiway trips. recently changed plugs and wires, thought this would help, how hard is it to change the coilpack, are there any other ignition componets that could be changed or related to ignition or this code.

thanks

If this is a V6, did you check the ground connection on the coil pack? If not loose, it could have some rust built up around or something along those lines.

Just a thought. Good luck.

Disconnect the spark plug wires, connector in the front and take out the 4 bolts at each corner. Remove. Reverse.
