I first started noticing the problem about a 6 months ago but it was
not as bad as it is now . I replace the spark plugs distributor cap
and rotor and air filer at that time and I didn,t see much of a
change. I just got use to the vibrating. Now it gets pretty bad. But
yes your right, The gas filter has 100,000 miles on it and the
ignition wres are the originals.
