Chevrolet Repair Questions? Ask a Chevy Mechanic for Answers ASAP
Hello, my name is***** vehicle has a timing chain, not a timing belt. The timing chain almost never causes problem so it sounds like you have something else giong on. Does your check engine light ever flash? Thanks.
The most common cause is a failed ignition coil. Check to see if each cylinder is getting good spark if any cylinders have no spark or weak spark swap coil's around on ignition module to see if spark problem follows coil. If it follows coil that means the coil needs to be replaced, if not that means the ignition module which the coils mount onto has failed. Let me know if you have more questions or if there is anything else I can do to help. Thanks.
