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 https://uploads.tapatalk-cdn.com/202...4664a00e54.jpg

Did you replace and retighten the bottom bolt on the DI computer?

Sure did.

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.
