That's the thing..the injector and the injector plug are brand new..I'm gonna get a compression test done cause I'm pretty sure it's cylinder damage but I'm more stumped about the shaking that's going on
I have a 1996 jeep grand Cherokee limited 5.2l. The check engine light came on and said that I have a mess fire on cylinder 6 so I replaced the plugs, wires, coil pack, injector, and injector plug but the light is still on and saying the same thing is wrong...also once I hit about 45 to 50 MPh...
