So the car's been running fine, bar a smoke issue that I'm getting to the bottom of.
Decided to do a compression test last night, all four cylinders between 175-178 psi which im really happy with.
But... after putting it all back together, and taking it for a rip...under full load it missfired like mad, engine management light flashed then stayed on and it sounded like a scooby!
It would continue to sound like a scooby(bad missfire) until I'd turn the car off and on again.
But any signs of boost it starts the process again
I re-assembled everything as It should be?!
