VX Starts ok, but runs terrible...

Yes, welcome to the family ... and to the adiction.

I'll second what MS said. Start with the more simple solutions and work upward from there. Most of that should probably be done anyway.

Replace the fuel filter
Replace the air filter
Clean the MAF sensor
Clean or replace the PCV
Clean the EGR system
New spark plugs wouldn't be a bad idea
Clean the Idle Control Valve
Clean the Fuel Pressure Regulator

Also don't forget to keep an eye on your oil consumption & on your CV boots.

There are threads on just about all of this. Let us know if you have any trouble utilizing the search function to find stuff.

spark plugs and make sure the wires are in the correct firing lorder. PO may have tried to do a tune up or something and put the plug wires back in incorrect the order,

The problem you are having sounds like a problem I once had. In my case though, I let the fuel get to low and the truck started running REALLY rough, SCARY rough in fact, and I got a CEL. I changed the spark plugs and that didn't help. I then went and filled up with a tank of premium and everything went back to normal. Are you getting a Check Engine Light in the dash?

your local parts store and have them see if you are getting an error code? That will be better at helping diagnose than any of us can do without actually hearing it.
