any ideas why my escort zetec seems to judder (not missfire) when i pull away from junctions? If just left to tickover it eventually cuts out as revs drop too low. Any ideas ?

help much appreciated.

 

I'd check the CO, if running really lean could do this, the fave areas are the PCV valve and the "T" piece at the rear of the head, both pennies to fix.

hi mate
ok well ive just changed the lambda sensor as id been driving around with a broken 1 for weeks. But it wasnt a new one (scrappies)

Where is the pcv valve? Is that the one on air intake near throttle body? cheers

sorry i now realise a PCV is crankcase ventilation, where would i find it?

 

It's at the front of the engine hidden between the exhaust manifold and block, unless they've moved it again!!

ok will have to check that then, cheers

 

any other suggestions while im on here? just so i can try a few to make sure
