P 0202 & P 0302

I just bought my first Jeep Wrangler a few weeks ago. A 2016 Wrangler 2 dr sport with 93,000 miles. Had it tuned up and serviced, was running great but then the engine light came on, it is running rough. My grandson checked it and it showed P 0202 and P 0302, what needs to be done?

Could be fuel injectors, could be spark plugs, could be bad wires. Take it back to where you had it tuned up if it was recent because they may have screwed something up.

I’d take a look at the Cylinder 2 injector and plug before anything based on those particular codes.

What did they do with this tuneup? May have disconnected Injector 2 and not plugged it back in correctly

The P0202 says #2 cylinders injector so probably a bad connection or wire.

The P0302 says a injector, spark plug on #2 cylinder.

A misfire isn’t always caused by the ignition system. The codes suggest it’s most likely an injector issue….probably a connector or damaged wire. The spark plug replacement is also a potential clue. Injector connector moved or damaged in the process. Things happen.
