thanks for your reply i am going to try a tandem pump next then a tank pump if i have no luck it ran perfect tonight on my 20 mile journey home yet ran terrible yesterday it was like it had a bent drive shaft on hard acceleration its very intermittent its got me puzzled i did find the one way valve on the fuel filter t piece was stuck open a few weeks ago i freed it off and have checked it since and it always seems ok i am tempted to try a new one anyway incase its sticking intermittently.

hi all i have a superb 1.9 tdi awx and it has developed a intermitent shudder during acceleration i first thought it was the dual mass flywheel so i fitted a full clutch and flywheel kit but it was still the same ive allso changed the injector loom and fuel filter i looked at the cam when i had the rocker cover off and that looked ok when it randomly happens and you then stop it feels like its idling on 3 cylinders for a few seconds all the power is still their and theirs no fault codes the car has done 138000 miles i suspect a injector but ifso how can you tell which one has any body come across this before. thanks
