icp possibly?

After my injector replacement and the truck wouldn't start I replaced the hpop with an adrenaline. I've bled the air and put approx 200 miles on the truck. When she's happy she runs amazing. But occasionally when coming to a stop she dies but starts right back up or when going down the highway the motor gets really quiet and will maintain speed but won't speed up for awhile. Stilm have air? Icp? Icp and ipr?

Could be ICP sensor maybe. Did you put new o-rings on the IPR when you replaced the HPOP?

Yep, new orings. It's gotten better the more I drive it. But I have a hunting trip next week and want it to be 100%

Look in the ICP plug and see if there is any oil inside the plug. Check the tin nut on the IPR that holds the solenoid on, and also check the engine oil level. Make sure it is full.

Happened to me this summer. There was a upgrade to AE and because I didn't have it the AE would not talk to my truck. I was pissed, called them and said that's why I bought one, to get me out of trouble when I needed it!! I'm on their list now to be notified when a upgrade comes out.

ordered a new icp yesterday. we'll see how it goes. Unplugging it made no change in idle or anything. I've heard both ways that that is ok if everything else is in good shape and that that means it's bad. I'll report back what happens.
