Had Service Engine Soon light come on. Showed DTC P0302. How do I fix this problem. The most enexspensive way. Put fuel injector cleanser in full tank of gas but still have 3/4 left to go. Advance auto tech reset computer and light went off. But don't know for how long.

What exactly does the DTC mean? I only know a few of them off the top of my head. Once we know what it means, I'm sure some of us can help you narrow down the cause.

It is a misfire DTC error code centering around cylinder #2.
