I've got a 1997 Ford F-350, the truck is running extremely rough and has absolutly no power, the truck makes a lot of bad clattering and bad noises. But it only happens intemintantly. If you let off the the throttle and get back in it, the truck runs fine for a few miles or a few seconds.

We have replaced the cam sensor twice, replace the ECM, tried a buddies IDM, and run codes several times.

The code that we have gotten is:
p0344 - (i think intermintent cam signal)

Is it possible that we have had two bad sensors?
What else could it be?

 

have you checked wiring to the injectors vc's and gaskets?
checked the tin nut that holds the ipr solenoid on?

 

p0344: CMP Camshaft pos sensor ckt intermittent Incorrect number of CMP transition counts Harness routing, charging ckt, sensor, int ckt, improper gap

Check the wiring going to the CPS.

 

I have same issue with a1997 F250HD., Will run fine then start bucking like a horse, then run fine again for a bit. This just started happening last night and today when taking it out,
I have a standard trans mission and about 147,000 miles. Low miles for a 97. Most miles put on it have been pulling 5th wheel.
Have not looked at it yet and looking for idea's on what to check.
Thanks
