I've been having some trouble with my SRT4 couple months ago my piggyback fried and then a couple days ago my engine light came on car running rough I knew something was wrong cylinder 3 injector not working I hope that the test light left wire light came on right where no light I believe this might be a ECU problem I ordered Predator 2 will be here today that fix my problems or do I need to buy a ECU to AGP Turbo 38 mm alter gate turbosmart HKS blow off valve turbosmart Plumb back RC RC 650cc injectors

 

My bad about the misspelling

 

I would try an injector first. And see how the engine runs.
