DESPERATE ED30 misfire problems

(1/1)

Jackged30:
Hi guys, desperate for some advice here as I’m not far from torching it! :fighting:

I bought an ed30 not long ago was fine for 2 days and it’s been a night mare since,
Misfiring from idle all through the revs, p300 301 - 304. I’ve cleaned the maf, vvt solenoid, had rocker off to check the timing and vcds phase bank1 was at -6, all marks lined up and I’ve done a new belt kit, chain kit with adjuster and oil rings seals ect, new iridium plugs @ 0.28, genuine black top coil packs but it’s still misfiring, Eml comes on if I hold revs at around 4k and flash for a while until I reduce revs again can’t think what else it could be if anyone’s got any ideas I’m fairly new to tfsi coming from 1.8t

Birchy:
Just a wild guess really but have you checked the engine earth points? If you’re getting a weak spark because the earth isn’t very good then it could get multiple misfires?

Jackged30:
I will check that next time at unit thanks mate

You need to scan it and Check which cylinder is misfiring. Most likely a fuel injector is dead I'd imagine.

All  4 are misfiring mate said up top got p301 - 304 worse as revs increase but especially worse at 4k
