Well. I can't believe im saying this but my tech has just called me. He popped the pre arranged maf sensor on. Has taken car to point where the misfire occurs three to four times admitting at one point to push it through gears.......NO MISFIRE ????????
My tech and I are flabbergasted. He's obviously not promising but may have just cracked it.
He thinks the maf was at early stages of deterioration so throwing weird symptoms out there.
I'm collecting car today hopefully and will give a good run tonight. Watch this space as they say....,,
Cheers again for your input. Great fully received.
