I asked this question before , tho maybe I didn't state it right I have
a 95 Ford aerostar with a 3.0 and I have bad vibration... now this
vehicle vibrates when you go to start the dang thing it vibrates when
you go to accelerate it tho it does better after it goes through the
gears its preety constant even vibrates at engine speed and very
noticable at the steering wheel and when you take off hear it at the
tailpipe ugh..  

anyway I have replace the engine mounts and the tranny mounts with no
good results .. the engine does have a slight miss but the engine
doesn't vibrate that much when you look at it .. but you sure can feel
it..

I replace the engine mounts when I first got the van .. but when I
started it up the engine didn't have any movement , but boy that
steering wheel sure did I could of made a milkshake it was vibrating so
badly That don't make no sense to me a engine that don't move yet a
steering wheel that does .. not to mention shake the whole dang van ..
ok I am open to suggestions?

P.s
and I did change out the sparkplugs so it does run better for those of
you that read my other post .
