2014 Jeep Wrangler mystery. I had code p0301 and p0302 pop up after hard acceleration. Drove it 20min to get home. About halfway home, driving up a hill it started running fine. No more issues On the rest of the drive home. I guess it’s not compression or spark. Maybe a new fuel filter? Anyone else run into this/
 
I don't think it's a fuel filter problem but possibly a tune up night be needed. When was the last one.

I don’t know. haven't owned long. 60,000 miles on it. I really didn’t think Just filter as much as fuel delivery. I’ll try a tune up. Thanks for the advice

Make sure you use OEM parts or the Jeep may reject them.

update for anyone who has the same problem. Replaces plugs, coils and injectors. That didn’t help. Started to get a tapping after replacing injectors. Waiting on a bore scope to check and make sure I didn’t drop anything in the cylinder. Replaced rockers and lifters. Had 3 bad lifters. I think the p0301 code is solved. Still knocking from the front of the engine. Seems most prevalent at the timing chain.
