I have a 1998 Ford Ranger, with a 4.0L V6, automatic, 4WD, supercab.

I was driving it, last week, and it died; just like I shut the key off. There was a slight miss in it, for a while, but it got really bad, and shortly after, it died. I pulled the coil pack, had it tested,, and confirmed that it gave out. I ordered a coil pack and installed it.

After installing the coil pack, it ran great. The miss was gone, so I figured that I fixed the problem. After driving approximately 10 to 15 miles, it started to miss, again. It died on the way home.

I used a test light to see if my fuel initera switch was getting power. After 2 - 3 seconds, I'm losing power. I looked through Chilton Repair Manual, and it says that my camshaft position sensor needs to be replaced. The part was cheap, but it looks like I'm going to have remove my intake to get at this thing. Yes, I know that it was easy to get at before they put the engine in the truck. [rolls eyes]

Is there anything else I should be looking at? If my description is lacking anything, please let me know, and I do my best to get it for you. Thanks, in advance, for any replies.

 

not sure if the 4.0 has one but my sensor was mounted on what appears to be a modified distributor shaft my bearing in the shaft on my 3.0 went bad caused an occasional miss and every now and then it would hang a little and make it stall. just a thought.

 

Yeah, camshaft position sensor makes since, or crankshaft position sensor if it has one?

 

Sorry to leave everyone hanging. Things have been really busy, around here.

I replaced the camshaft position sensor, which included removing the entire intake. Since I had the intake off, I figured that it would be a good time to clean everything.

It turns out that the camshaft position sensor was not the problem. Eventually, I found bad connection in the wiring, underneath the truck. After repairing that, the truck will start and run.

Now, I have another problem. The truck will start. It will run, after it warms up. The fast idle is not working, now. It also seems like it's idling too low.

What should the engine be idling at? Thankfully, I do have a tachometer, so adjusting it won't be hard.
