Hi all. Got the car back from the body shop and I'm back on the road. I have still a problem with SUP and would ask if you could help point me in the right direction.

 

Revs can infrequently be jumpy between 400 and 750 rpm when stood still, a backfire or over rich exhaust bang which is uncommon but related to the latter, reaching 1.2 bar no problem with the FCdefencer in place before rev idle concern, progressing to backfire progressing to fuel cut and 1 bar max on a cold morning? Issue was raised a while back as a throttle sensor concern poss. I am trying to contact Leon on the land line number > a mobile would help as I fear that may be the next step. Could be 2, but I'm sure she's drinking more 2....

 

thanks you all.

 

Mid.

Well if it was boosting to 1.2bar ok before but now only getting to 1bar before hitting fuel cut, I can't see how it could be anything else but FCD related.

 

Lumpy idle/backfire IMO is the majority of the time spark plug related.
