I need to know what a 0202 and 1249 codes are......
This thing is running like crap. I am guessing a injector died... I heard a slight knocking for the last 500 miles.....Now its pounding.

How many times are you going to post this?

P0202 is injector #2 drive fault. P2149 sets when injector 2, 3, 5 or 8 DTC is set. When a fuel injector circuit condition is detected by the FICM all of the fuel injectors on the affected injector supply voltage circuit will be disabled.
