Powerstroke 7.3 problems.

This will be hard to explain in english for me but I'll give it a try...

My -96 powerstroke has started to missbehave latley.
The engine runs great but suddenly it's like the ignition shuts off for a half second then on again...

It can run well for a while, then this problem starts and it happens a fiew times in a row and then it runs as it should again for some time, etc.

I checked the connection to the "solinoid-thingee" that shuts the diesel and that was a bit wet because the diesel filter was leaking. The filtert is fixed now and I changed the contact after drying it out and for a while I thought I fixed the problem but nope.

Is there any other obvious thing I should look at? It feels like there is som bad contact somewhere around that shut-off-solinoid (I dont know the english term for it...).

sorry bout my english.

Try changing the CPS (cam position sensor). They are a common issue for our 7.3s. So when your driving down the road, all is normal, then it feels like the engine shuts down for a second, then comes back to life and runs perfectly normal correct? I would say CPS all day long.

There is a possibility that the ICP sensor could be causing this too. To test that out you can just unplug it and go for a drive and see if anything changes.

The CPS is located at about the 10 o'clock position close to the harmonic balancer. It has one 10mm bolt holding it in. Pull the 10mm bolt out and the CPS is free to come straight out the front. Sometimes you might need to twist it a little to free it up or even use a screwdriver to easily pry it out of it's bore. Installation is easy. Put some fresh motor oil on the o-ring of the new CPS, install into front cover, snug down 10mm bolt, and plug in the sensor.

Go to Ford for the sensor. Don't try any of the parts store sensors b/c they will do nothing but give you problems.
