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.
