this is really frustrating me now, i have a afm lined up just gotta purchase it but unsure if it actually ok.
cars normal when cold, but once warm just dont go anywhere (no boost) idles perfect and everything else is fine. happens round 2500- 3000rpm. can the afm play up like this only once warm? car will go on to dyno to search for the fault (fuel related) if afm cant fix and there arnt any other opinions.
but does anyone else have any more ideas, fuel pump wouldnt do like this surely?
