Joel,
Check all the basic stuff first
as listed in the Bentley Service manual.

Make sure that all of your components
are good in the ignition system, primary and secondary:

Coil
Distributor
Rotor
Cap
Ignition Wires *************
Plugs

Check all your ignition circuit connections:
at the coil and at the distributor.

Make sure that you have good plug wires!!!!!!!!!!

Hey gang,

I'm trying to help out a�buddy with a 86 2.1Ltr. Westy.� 

The van�idles great hot�or cold and starts right up.

While driving along all the sudden it will hicup and miss loosing all�RPM
under load. And pick right back up.
When slowing down to take a turn�and picking up speed it will buck and miss
with some backfiring.

I have checked the wiring and it all looks good. I have�also checked�and
replaced the easy things�like:
New�TempII sender and�
I swapped a good AFN (out of my van) AFM 
A good Idle Stabiliser relay

but the symptons are�still there.

Any hints where and how�to track this gremlin down?� I will swap the brain
next and the O2 is new.

Thanks,��
�Joel Cort
