I'm sorry you are having problems with your vehicle. I will try to help.I'm a full time mechanic and have been a mechanic for over 20 yrs and I work part-time here on JustAnswer to help you and others repair their own vehicles, and I get credited by your ratings.. So before leaving the site make sure and leave me a rating. You can still reply to me as many times as neeed, even after the rating.. I will need for you to be my hands and eyes since I'm not there.It sounds like there is a dead miss. Possibly caused by bad wire, defective new spark plug, miss routed wire, or cap and rotor.Did you replace the wires and cap and rotor as well? Or just plugs and filter?I strive to provide 5 star service. If I satisfactorily answer your question please rate it as such and hit submit. Doing so is the only way I get compensated for my time. Also it doesn't close the discussion so we will still be able to communicate if there are further questions.
Thanks
Sonny

Im thinking it may be a vacuum problem
Ford Mechanic: Master Auto Tech., master tech. replied 8 months ago
Ok, no prob. Usually a vacuum problem will cause high idle. Shaking violently usually is a dead miss.
Does it rev up ok and run fine or does it seem like there's no power or less power?

what could cause a dead miss
Ford Mechanic: Master Auto Tech., master tech. replied 8 months ago
Many things, but I'd assume first, that it was something that was messed with.
Like the wires being damaged, a defective plug, or a wire put on the wrong plug. Like cyl 1 wire put on cyl. 2.
Did the plug wires come off hard or were the wires pulled on and not boots on the end? And are they definitely on the correct plug?

See which cylinder is misfiring by doing a cylinder balance test.

First of all you will need a 12-volt test light and about 8-12 inches of neoprene vacuum hose. The vacuum hose will conduct electricity cause it is carbon based, use an ohmmeter if you are not sure and see if the vacuum hose you have will conduct.

Now, cut off the same # of cylinders you have in small equal lengths of the vacuum hose. 2-3 inches will do fine. The small diameter kind like to carburetors, etc will work as long as they fit over the distributor cap tower connection.

Now, mark all your spark plug wires at the cap or coil pack and remove them all. Put those short pieces of vacuum hose on the distributor cap or coil pack connections and shove the other end of the vacuum hose into the spark plug wire boot until it makes a good connection.

Now connect your 12-volt test ground clip to a ground and start the vehicle. With the engine running touch the 12-volt test light to each of the vacuum hose 1 at a time and listen for the cylinder to short out and die and drop in r.p.m. They should all be about equal. If 1 or a few don’t drop or do anything than you have your dead cylinder there.

Because of your expertise, you armed me with enough ammunition to win the battle with the dealer. They are installing a fuel filter and fuel pump at no charge to me.
