Here's a great problem that im sure other people have suffered.
OK, cold hot fast slow, under boost or idle the engine will stutter and loose power for a split second, sounds almost at idle like 2 cylinders have dropped out, you can watch the engine buck and hunt!
As soon as it started doing this, its got worse and is now at the point where in a 5 min journy the idle will go nuts and it will misfire if you like at least 3 times and one of those times severly.
I cannot understand this as performance is good all round and i achive 700 miles to a tank of diesel! (when it was or at times plays ball)
MAF checked disconected and reconected, performence good connected but always had a slight cap on the power at 2500-3000, thought this due to unrefinement.
throttle pot ok and will progress smothly with correct rpm (car shudders slightly at 2500......magic number!)
egr piston working and vacumn from unit ok (vacumn unit makes high pitched ticking sound?)
throttle vacumn ok
turbo makes all the right noises, variable vane system...pass...but good boost pressure!
fuel pump working and makes correct noise.....
So now im stuck.........fuel filter responsible for all this?
HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
