E250 Knock Sensor location / fuel injector pressure

I have a 1990 e250 6 cyl. 4.9L van. Could anyone verify that the picture at the following address is the correct KNOCK SENSOR and describe its location:

If the sensor needs replacing would it cause the van to run hard and be difficult to start.

Thanks for any support.

Thanks Steal One.

As you have no doubt noticed I've not been too active on this forum (thanx to the forum for reminding) due to the lack of response to my post. Since my original post I located the knock sensor. A mechanic had told me it was cracked but I could find no evidence of a crack except on the wire, which didn't seem like a big deal.

I got the vehicle running ok, after sorting through a series of problems, but still can't figure out what I now know is the main problem: the fan blowing hot air back onto the engine (under the cowl), causing the engine to heat up (though not overheating) and causing what seemslike a failure of the oxygen sensor, because the vehicle then runs poorly, especially when I turn off the engine for a short period, then restart it (like when buying gas).

I will bring up this topic in a new thread and see what response I get.
