Hey All,
My '89 Vanagon has been sluggish, hesitating, surging and missing out
when I press on the throttle (or accelerate).
When I let her sit for at least an hour, she seems to do better and
then once she's heated a bit she does it again.
She has been sluggish when I start her initially also.

I have replaced the fuel pressure regulator, fuel pump, fuel filter,
spark plug wires, spark plugs, rotor, distributor cap, all that good
stuff and she ran fine for quite some time then this misfiring problem
cropped up when it got colder and I also have a leak where the oil
cooler O-ring is so I bought a new O-ring and plan on testing the oil
cooler for it's proper functioning and then reinstalling it with the
O-ring and AMV sealant.

I have been considering it possible that the fuel injectors are dirty
so I'm looking into rebuilt ones and is there any way I can rebuild and
clean these myself?? If it's possible is it cost worthy compared to
buying completely rebuilt ones??  I was reading about the throttle
valve switch being out of adjustment and possibly just bad, could this
be the culprit?

Another thing is that with this leak at the oil cooler I wonder if
during the winter months especially if I should be using a single
heavier weight oil than the 20 W 50 I've been using?

Thoughts and expertise would be appreciated.

Peace, Love & VW Grease,
Sunshine
