2005 Chevrolet Monte Carlo Question: IGNITION COIL
Answer #1mastertech6371 June 15, 2010, 18:51Master
if in fact it is the coil. you need the code for the cylinder missfiring and need to eliminate the plug and wire before looking at the coil.

Your engine is a V6 that shares a coil per two cylinders (3 coils total). A scan tool is needed to verify which cylinder is experiencing a miss fire ie a code P0301 is cyl 1 mis fire, P0302 is cyl 2 misfire, P0303 is cylinder 3 misfire ect.....
Roy is right mis fire could be due to other things an injector not firing a vacuum leak, a plug or plug wire.

If you are willing to pull the spark plugs 1 at a time. Look for the dirty 1 and start there by replacing it.
