2005 Chevrolet Monte Carlo Question: IGNITION COIL

CAN I FIND OUT WHICH IGNITION COIL IS MISFIRING AND IF SO CAN I REPLACE JUST THE ONE -
Answer 1
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. Roy -
Answer 2
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. -
Answer 3
If you are willing to pull the spark plugs 1 at a time. Look for the dirty 1 and start there by replacing it. -
