hello all,

thanks for your responces,

found o2 sensor was faulty by checking live data, found points its dropping off to 0.00v then up to 65v and really slow to react under reving. Replaced and was working fine when the car was running fine.

came to the cranksensor due to there being no other fault codes in the abs or any other system, and i was sure it was the rear right wheel that was the the VSS, must be wrong then. (ok i was cutching at straws with that one.

its had a oil change and fush whn the head was done. but its weird since moving the wires it hasnt done it since. Customer got it to try and hasnt herd anything since. so will report fixed if i dont here anything by the end of the week.

thanks again
mike.
