It is probably a spark plug or ignition coil issue, but we should run the codes to see what comes up, there is no fuel filter except for the strainer inside the fuel tank.

Here are two guides to help us fix the problem:

Spark Plug Type .................... GM P/N 12590701

It could be a stuck fuel injector so take note of the spark plug condition, the one that is different will be the cylinder that is having a problem.
