we have the same van for the last three months we've had very similar problems had a knock sensor code also. ours never died but started acting like it was'nt going to start would never do the surging or rough idle when we got to the shop almost as if it new what we were trying to do. we did how ever find out that it was the EGR valve. that it was sticking wide open when it got warm. the dealer no longer makes this part they do have some like at auto zone for about $167.00
we also changed fuel filter,plugs,plug wires, cleaned the throttle body and replaced the Throttle position sensor.
the guy thats going to fix the egr valve said it could have also been the fuel injectors or the fuel injectors needed to be cleaned and o rings replaced this is not the case with our van but that was his first possible diagnosis.
if you go to church you might find someone with a mechanic shop or some one who can help. our church has a car ministry with mechanics that often do some side work which is a blessing. hope this helps

Do not ever replace a knock sensor. They can not cause any driveability problems. Other things cause the sesnor code to set

snorkelbobby can you help or anyone else? I just purchased a knock sensor at Checkers for my 2000 Mercury Villager. I started having problems yesterday when the traffic was backed up. Lots of stalling, the van dieing on me, lots of hiccups and etc. I immed drove it to Goodyear and they ran a diagnostic and told me it was the knock sensor and that the intake manifold needs to be resealed, and a new valve cover gasket?
I drove it again today and the van died six times and took a few attempts to start just driving a 1/4 mile. In between all of that I had a lot of close calls with it dieing. Like I said this all really began yesterday but for the past couple of weeks we would have a slight hestitation every now and then when driving.

Hey guys, I had the exact same issue with my '99 Villager. It would run fine at cold start up but as soon as it would warm up a bit, it would misfire, and chug at idle. It would smooth out somewhat under acceleration but the problem was always there. I tried a new cap, rotor, plugs, cleaned the optical sensor inside the distributor, new EGR valve, a couple of fuel injectors and it didn't help. At times, it would generate a check engine light (random miltiple misfire code) and when I would clear it, sometimes it wouldn't even generate a code for a while, however it would akways run rough. Anyway, it turned out to be the distributor! I pulled out the distributor and there were shavings all over the gear. I did some research and apparently they are known for failing. The heat tends to take a toll on the coil and knock sensor (which are both inside the distributor) and combined with the gear wear, it can cause a misfire code due to excess play. I put in a new distributor and the problem is finally gone and It runs good now! This problem plagued me for a couple of years and even a couple of dealerships couldn't find the problem. Buy one on eBay, because they are not cheap. It sounds like that is your problem as well.
