My '85 Vanagon has been idling rough for a few weeks =
now. I found the problem being a bad spark plug wire (resistance =
was
infinite). I replaced the spark plug wire, and replaced the old =
worn-out
Bosch spark plugs with new Bosch Platinum plugs. It =
seemed to me
the engine was idling a little rougher then if I would have just kept =
the older
plugs in, but it might have been my imagination.
I then adjusted the timing and took it out for a =
spin.
The problem I am having is there seems to be no power at the lower =
speeds and
the Van is definitely getting hotter then normal when at an =
idle.
So I have two theories. The first is I am =
doing
something wrong with the timing. The second is the spark plugs are =
problematic.
The timing on the van is really weird. If I =
set it to
the correct timing, the car idles poor and requires the use of the idle
stabilizer. If I adjust to more before TDC then recommended, the =
car idles
much smoother and can maintain 850 RPM even without the use of the idle
stabilizer.
So what do you guys think. Should I adjust the =
idle to
be more BTDC for the ride home, or do you think I need to replace the =
spark
plugs? Or some other problem?
Thanks!
