Gday all,
As above the car seems to chug under load. A slight hill doesnt seemt o be a problume if you kikck it back a gear, but if a back off fro a bend it stsrts chugging like [!Expletive Deleted!].
At ideal its fine and revs freely when not in gear.
Changer plugs, leed ,coil vacume advance ,and fule filter
amy ideas?

petergalileo:
Any smoke from the exhaust ? Air filter okay ? Any warning lights ?

muddydigger:
No, there is no smoke from the exaust, and no warning lights either. Air filter is near new but I did check it just incase and it seems to be fine.
The airflow meter is a reconditioned on and has run well untill a week ago.
It does seem to be rich and is using alot of fuel.
So Im thinking fuel mixture, fuel pressure or timing.
Replaced plugs, leeds, coil and fuel filter no change.
Any other ideas?

petergalileo:
If you think its over fueling I would look at the engine temperature sensor as the ECU uses that to judge the "choke" position.  Also check for intake vacuum leaks, specially the pipes going to that little plastic ball.
