P1263, p0304 after spark plug change
Have changed spark plugs as I have a misfire.
I'm waiting on new coilpacks but was hoping the car would get better with new plugs. All I have done is change the spark plugs and straight after went for a test run. A full throttle pull in 3rd got a few pops then nothing, almost like someone turned the key off. I managed to get it home by resetting / clearing the codes but it only gives me 2 seconds of throttle before going into limp mode again. Any help is much appreciated  Sent from my SM-S908E using Tapatalk |

If you haven't already done so, check the connections to the DI computer and to the direct and port injectors, esp #4. There are 2 other ground straps. Check them too.
