You need to get the car scanned for fault codes and even some live logging when the problem occurs.

Atleast i'm not alone then in my misfire adventures  :pomppomp:

Having it scanned and looked at by AMD on wednesday morning so hopefully get the bottom of it, am i right in thinking there was somebody on here that had an AMD re-map with this problem and switched to REVO and it cured it??  :confused:

yes my missfire apprentice  :laugh:

its going back nect week , they want it for a day and a half to change my spark plugs and coil packs ?
now i dont want to tempt fate here but they do know where my engine is on my car , dont they?
considering i dont have an engine cover i was thinking 40 mins tops to change them al out , so god knows why they need it for so long.

not long now for you Mike , i bet this weekend is dragging on?
