Hi.

Hoping some of you pros can help me out, or offer a suggestion. For about the past 2 months I have had the following issue, and I'm trying to pin it down without going to the dealer$hip first.

Occasionally (probably 1-3 times a week) the truck will suddenly lurch as if it has died in mid-stream, and then start running fine. This can and has happened while merging with traffic on an on-ramp at 40 mph, or at 65 while cruising down the highway. The guages drop to zero for a split-second, and then back to normal, and the truck lurches violently. I initially thought maybe something going with the tranny, but then yesterday...

While pulling into a parking lot at 2-4 mph, the truck did it again, and this time, completely died, and rolled to a stop. If I put it in Park, and restart, everything's fine again. First time I've had it happen at low rpm, though, so I'm wondering if I have an electrical problem.

Items recently done to/happened to vehicle:

• New pressure hose on power steering pump about a month ago.
• Cruise control went out about 8 months ago. Haven't bothered to fix yet. Think it's probably a switch.
• Both batteries are about a year and a half old.
• Fluids are fine, and tranny fluid smells/looks great.
• 124K on engine. Oil and filter about 4K ago.

Has anyone seen this issue before? Injector going bad? Truck runs like a top otherwise, and after the initial hitch in the get-along on occasion, it doesn't hiccup any more. Usually within 4-5 miles of startup this happens.

Thanks for any and all suggestions.

 

I would bet its a cam sensor. and even if its not then you will have a spare for when it does go out. its a very common failure and has the same symptoms as a failing cam sensor. stall, bucking, with or without restart, totally random

 

Sounds like the CPS (Cam Position Sensor) is going out on you, Replace it before it leaves you stranded on the side of the road. Most everybody on hear carries a spare CPS with them. You can get them for a pretty good price on ebay, buy two one to install and one for a spare. If you have to have it now and can't wait on ebay, get them from your local International Dealer, they are cheaper than Ford.

 

tj, your just to fast for me.

 

Thanks to you for your replies.

After digging a little further on this site, and finding a couple threads with the same issue, I totally agree with your diagnosis!

I'm gonna get down the the local IH dealer here in FW, and see if they can get me fixed up.

MANY thanks for the input, guys!

there's the part numbers for your viewing pleasure

 

Just a follow up to say that the CPS appears to have been the issue. Grabbed one on eBay, and threw it in there, and the problem hasn't reappeared in a week.

Thanks again for the help, guys!

 

great to hear! keep on truckin!

 

wher is the cam sensor located on the block.I am having the same problem

 

The CPS is located on the front of the engine. If you look around the crank pulley it sits at about 10-11 o'clock. It has a single 10 mm head bolts that holds it one with a three wire connector. its hold down bracket serves a a pointer for the cranks pulley. Its easiest to see from the bottom and I usually change them from the bottom. Its also easier for me to take the belt off the engine as well.

 

how can i tell if the one in the wrecking yard is the right one that I need. 96 verses 97 etc? Will it have a number on it?

 

If you mean you are getting a CPS from a junkyard you better get it for free. They are very cheap now. See here.

It will fit any 7.3. if you get one from a junkyard it may or may not be any good and yes a '96 will fit a '97

 

hey 4k? change that oil!!!

 

You lost me but that is easy. The dates for these are old and I hope they have changed the oil since then

 

you lost me for a minute, good lord they are! dont mind me
