please help, my gti is juddering like its starved of fuel with a full tank

[pascoe]

hi i have a 1.8 8v gti and when its warn and at high revs over 4000rpm or low revs under 2500rpm it judders like its being starved of fuel but its got a full tank and i was wondering if its a fuel pump problem, injectors or sumthing, any ideas

cheers pascoe

first thing I'd try personally is the fuel filter!

[pascoe]

o yeah didnt think of that, will get a new 1 mondey and see if thats it. cheers

I doubt its the fuel filter if it only happens when warm.

Is it K-Jet or Digi?

[danny_p]

check the lift pump

check the lift pump

As above.

Good call! - didn't realize he said about it being warm!

[pascoe]

thanks for the replys will try the fuel filter tomoro just in case because its the cheapest lol if it doesnt solve it will have to try the lift pump.

and myt be a silly question but how do i know if its a k jet or a digi?

thanks again.

Airbox is the biggest giveaway I've always thought. Someone correct me if I'm wrong.

Digi - Has the box maf sensor on the top


K-Jet - has a load of hoses coming from the airbox


Hope this helps.

This may help with the fuel pump diagnostics too.
