Hi Lister’s,

I’ve included a link to the sound of  engine running badly.  I’ve at least gotten it to start and run poorly.  Maybe the sound will give some hints.

It seems to surge and vibrate.

I have now changed the fuel filters.  And I check the AFM connector and while they're put in a new air filter. 

Van starts if I feather the gas.  Runs with careful feathering. Will eventually idle but now surges and eventually stalls. Runs with vibration.

Some progress is being made but not sure where to look next. 

I will have more skilled help later in the week. We will have a  multi meeter and a  gas pressure tester.

Tips appreciated.
