Cam sensor?

[blowinsmoke7.3]

New fuel filter, new frame mounted electric fuel pump still no luck Truck loses power when accelerating. Will cough and choke then all of a sudden it picks up and runs fine. Only when accelerating. Idles fine. No other problems except when accelerating. Could it be the cam sensor?

Have you checked your pickup screen in your fuel tank for crud? Your symptoms don't sound exactly like a clogged screen, but if your fuel level is low enough, it's worth a look. Have you also tried scooping up a new CPM & give it a try to see if it clears up anything? If you've got a grey one installed on your rig, you should have another one for a spare, anyway.

Truck has a full tank right now You mean CPS? Arent those pricy?

Failed to mention that from time to time the truck also develops a sporadic idle. Will jump from 1200 up to almost 2000 at times then back down to almost shutting down. This isnt all the time though. Maybe 1 in every 10 starts or so

Do you have a resistor in your ICP?

If so I would take it out.

your symptoms aren't caused by the CPS. you may have a bad ICP sensor or your IDM is dying.

Actually, I agree with sldghamr's reply. I remember the same thing happening to my IDM last year, but it happened a lot faster & the truck died within 10min. If you can get your hands on a scan tool with functional test capability, I'd run a buzz test & see if any IDM codes pop up.

Had one at one for a short period of time but didnt like it at all. Took it out long before this stared. Could that have anything to do with this?

[Southpaw]

No I doubt it. Not if it came out a while ago, and you didn't have any problems til now.

sounds like icp issues,do like radar rider says and scan it and see what your icp is doing.
