So for the past few weeks the Z has been backfiring heavily when coming down the rev range in any gear - without being pushed at all (just shifting down a gear and leaving it come down on it own).
Recently i had the O2 sensors changed by Jimmer and some fresh turbos and it is more or less since then.
I have bought a brand new MAF from Z1 and just changed the spark plugs all-round.
Im also idling around 950 rpm, and can hear some break-up in the exhaust tone every few moments.
Any suggestions on what to check next?
91TT Btw.

I also bought a MAF from them last week - fedex messed me about for days claiming they’d attempted delivery but again, no card, and I was in the house all day and not a peep.
I had been trying to contact Z1 prior to this going back a couple weeks and not had responses to email - and can’t connect to their phone number either.

Constant Backfires and some spluttering on idle

Thanks for confirming, not getting any continuity through it. Perhaps it’s dead..
