Took caliber to dodge dealer, they changed #1 cylinder fuel injector, but light came back on after 30 miles. Leak test showed 45% leakage in cylinder 1&2, car is running fine. Doesn't make sense to me. Help please.

Answer 1

P0301 Misfire number 1 cylinder

45 % leak down you would slight rough idle , but at highway speed or acceleration it would run great. There is 2 area where the leakage can be from , one is the cylinder valves or  crack in the cylinder head between the exhaust valve and intake, or the cylinder rings which is more than a unlikey possibility, you be be burning oil.
