On a 1995 Ford Contour :
According to one of Ford's websites :
The spark plugs on the 2.0 liter four cylinder are gapped at ( .050 inch )
For the 2.5 liter V6 ( .054 inch spark plug gap )
you don't, you buy a chevy.
You have bad spark plugs and or cap and rotor
There are a couple of reasons why a 1999 Ford Contour may misfire. The spark plugs may need changed or the coil pack may be bad.
A Ford Taurus and Contour are a couple. (1997 Taurus with the 3.0 liter engine & 2000 Contour with the 2.8 liter engine)
1.13 mm or .050 That's the gap my plugs are running at on my '95 Zetec (Motorcraft plugs)
Change air filter and clean or replace spark plugs
Does a 2003 ford expedition have spark plugs?
ok 2.0 is .050 inch and the 2.5 is .054 inch gap
I WOULD SUSPECT THAT ONE OF THE PLUG WIRES IS NOT MAKING CONTACT OR IS NOW BROKEN.
Check the Vehicle Emissions Control Information ( VECI ) decal located in the front of the engine compartment ( it will show the type of spark plugs to use and the spark plug gap )
It could be either a bad fuel filter or fuel pump or it could be bad spark plugs or cap and rotor or spark plug wires
It has spark plugs. They are just hidden from view.
