Hi Mark

Of course you are correct, I didn't notice that before.

Glen

You need to take channel B off AC coupled.

'If I had the sample rate faster it was clear that there is a small ammount of shift between cam and crank'

Under what conditions can you see the sync shifting?

How often does the fault code re occur?

Has the customer experienced any other symptoms other than the MIL being on?

If the code is re occuring then under what conditions does the MIL light up?

Is this the first time the MIL has been on in 300 miles?

Can you post a capture when you have seen the sync shifting? and point out what the conditions were at the time. ie, cranking,idling ect.

cheers
James
