everytime my focus revs over 3000rpm ish the car begins 2 judder and wont accelarate or rev anymore, this happens in every gear, anyone able 2 help??

 

What engine?

Might be worth checking the pipe on the back of the manifold that goes to crankcase breather on 1.8/2.0 zetecs. The pipe collapses on the bend by the manifold.

failing that, coil pack breaking down?

 

possible MAF as well, depends on engine really.

 

Sounds like Cat Collapse tbh.

 

its a 2litre focus st, i have to keep the petrol above quarter of a tank due 2 a low pressure fuel problem, could this juddering be related to the fuel pump aswell??

 

Have you checked your spark plug's/leads/coil pack?

this can cause a juddering sensation

 

Hi

My focus st170 has had lean fuel problems and engine management light come on. Found a split in the Crankcase breather pipe today.

Anyone know where I could get one from? Ford have told me they don't make them any more

Cheers
Chris

 

If it's split, can you not join it with copper pipe and jubbly clips?

 

Yeah, they are different to the ST170 one mate.

 

bugger, that was quick posting, didn't even give me time to check and edit! lol

 

Haha, yeah, I'm searching the net for one. Can't get one anywhere!!

 

Do you know whether I can use something like this and cut it to size if I find out the hose diameter (bore)?
