rough idle & shutting down

[05wh250]

Alright guys my grandpa has a 96 with 154,XXX on it with a superchip. Its idling rough, as in it will lope for a few seconds then almost smooth completely out then go back to loping and just do this continually, he said it would shut down randomly when idling but start right back up. I pulled codes with the superchip and it had one for the cam position, one for the boost sensor and one for the ebp sensor. So I put a can position sensor from Napa in it Sunday and it idled and ran great. Then yesterday he called me and said it was right back to the same thing, so I scanned it today and the only code it had was one for the ebp sensor. Did I get a bad sensor? And where is the ebp sensor located?

You might try a CPS from Ford or International. There have been many cases of aftermarket CPSs being bad right out of the box. The EBP sensor is located almost on top of the HPOP Reservoir, passenger side. There will be a tube running from it down to the passenger side exhaust manifold. Sometimes the tube gets clogged with soot. It removes fairly easily and can be cleaned with carb cleaner and some wire rope chucked in a variable speed drill (like a plumbing snake). You could try unplugging the EBP sensor to see if it stops the lope cycling. You might also try removing the chip and see if it stops it. Cheers!

Patrick gave you good advise.

Try unplugging the icp sensor if the above advice doesnt work. See if it has oil in the connector. Wouldnt hurt to clean his fpr screen either. And always xould be injectors, but like stated, get a ford/ international
