One problem related to check engine light on has been reported for the 1996 Chevrolet Monte Carlo. The most recently reported issues are listed below.
Bought car July 12, 1996, July 29, 1996 broke down due to #6 injector staying open. Replaced. Sept 9, 1996, found improper leak down rate on fuel injectors. Installed fuel injectors. 34,610 miles check engine light on, found #3&5 cylinders misfiring. They put injector cleaner in. 40,323 miles #1,#3 & #5 cylinders spark plugs & wires burned. 43,000 miles #2 cylinder spark plugs & wires burned. They want me to pay for this problem, but why do they keep burning out. Have 2 more to burn. Called chevy, they said the same wires have to burn twice. I saw many complaints about this on NHTSA website. What does it take for a recall. People shouldn't have to pay for same problem. Why didn't they change all spark plugs and wires to all cylinders. Have to keep going back. $108. 05 for each cylinder. Never heard of this problem on any other car. From day 1, car has started hard, nobody can figure out why. This car is not yet 3 years old, I would like to keep it longer, but not with this happening.
