Help for my 97 PSD. It has an intermittent miss (cut-out) at no or little load throttle. Seems to be getting worse and bucks sometimes with cruse control set. New Ford CPS installed and almost new Dorman TPS. No other symptoms noticed and seems to run fine otherwise. Any help or suggestions would be greatly appreciated!!!!!!!! Thanks all!

 

have you checked/replaced your speed sensor on top of the rear pumpkin? only 30 bucks i think...? just a thought..

 

How recent fuel filter change? How about oil change?

 

How about some more information: mods, miles, trans, any stuff thats in the signatures.

 

Stock 7.3, 230,000 mi. 4X4, E4OD, with 3" Diamond eye down pipe and straight 4" exhaust. Filters and oil changed recently and after problem started.
Thanks again!

 

Have you tried a new ford or IH cps? Cheap easy try, and they are known to do some weird crap, along with you need to carry a spare, they are that common to fail.

 

Check the TPS with a mutimeter and look for any dead spot in the voltage.

Put the hot lead on the middle wire of the TPS and ground on NEG. Side if battery. Turn key to run and slowly push the pedal and watch the voltage

 

Brand new Ford CPS, no change. I will check TPS voltage. Thank for all the help guys! I bought my truck with 160,000 miles on it and I love it!!!!!!! I, looking to "chip" it soon and install an intercooler. Thanks again!!!!

 

TPS reads very steady increase and decrease in voltage and according to specks. Your help has been greatly appreciated, Thanks again!!!!!!

 

Have you check the plug and wires to the CPS real good ?

Your probably going to have to get it on a scanner that can see live data to see what the HPO system is doing

 

Have you checked the fuel pressure at idle?

 

I understand that it takes a higher end scan tool to read the PSD's, is this true? I've been looking at them but there are so many to choose from? I'm open to suggestions?

 

Yes you'll need a good scanner.
I use the areoforce scangauge it around 250
If you have a laptop you can get a AE for around 250
Both of these can be picked up from clay at riffraff
