Default P0302 Misfire

2001 blazer 4 x 4 check engine light on. popping a P0302 code. #2 cylinder misfire. pulled spark plug and it was wet fouled. Changed #2 plug and after clearing al codes it popped a P0302 again. also replaced plug wires and dist cap. Could it be a fuel injector stuck open?

You need to make sure that you have 1" of strong blue spark at that cylinder.

Have you done a compression test?

Yes you may have injector issues, the sticky on testing is a good start. If an injector is stuck open you will see rapid leakdown
