You know, as odd as it may sound.
Having had the same problem with my 91
After I power sprayed everything
the problem went away.
Bad electrical connection I suppose.
( can we say grounds? :o)
Yes, first things first
I changed the fuel filter
& tuned up the engine.
Although I didn't change the spark plug wires.
And this is breaking my own rule.
Because I've had lots of trouble cured
by taking this magic new spark plug wire elixir!
YMMV
