I am having rough idling problems with my 93 Mercury Villager. I have done the standard tune up. It was still rough so I cleaned the egr valve and it ran ok for about a week. I think I should buy a new one, but after pricing them, I found out the part is a bit pricey and hard to find. I don't want to spend a lot on the vehicle. Getting rid of it within a year. I have priced an egr valve of the same year on a Nissan Quest and found one that is cheaper than the Mercury Villager. I would like to know if it will work.
What will work temporarily, is to remove the vacuum lines and hook them together, stopping the vacuum leak in the EGR because you've bypassed it. That will work till you can find a new one, or good used one and get it changed. Now you can say "why didn't I think of that". Seriously, friend, it's just Exhaust Gas Recirculation valve. it won't hurt anything to bypass it for a little while.

Check the timing, PCV, fuel filter, clean out the throttle body, air intake, and check the Exhaust gas recirculation system. Valve and all.

Fuel Tank Filler Pipe
The fuel tank filler pipe is of steel construction and is retained to the vehicle by means of two lower retaining bolts and one upper retaining bolt. The fuel tank filler pipe is fitted with a twist-fit filler cap, which seals the system.
I would not replace it unless there was a reason.
Check EBay or tascaford.com if you really want to replace it.

check the spark plug wires, put water in a spray bottle and spray along the wires,especially by the coil,if the car starts to run bad or you see sparks, the wires are no good, hope this helps, Ray

You need to replace your distributor. There has been many problems with these. I had the same problem with my 1993 villager and had tried many different things and none worked. I went to a junk yard and got a used distributor and now it runs fine. I would try this before anything alse.
