U1016, u1026, u1064

Hello.
I've started having yet another intermittent problem. Car starts fine, after a few minutes I depress the accelerator and the engine won't rev. After 15-45 seconds it goes back to normal and runs ok. I currently have codes U1016, u1026, u1064 as well as a p0449 which I don't think is related.

A few weeks ago all dash lights came on and the gauges went dead and the radio had no power while driving, but the car continued to run. I turned key and everything reset.

Any thoughts? Thank You in advance.

Please Review the Classic Video linked below produced by Will Robinson on "How To Diagnose Class 2 Network UXXXX Codes" and follow his Step By Steps for Isolating BOTH Splice Packs:

(1) Located under the Driver's Side Knee Bolster on the Left Side:



(2) Located under the Passenger Right Rear Seat ...under the Carpet Flap:



These instructions will help to isolate ALL of the Modules in the Vehicle in both the Front & Rear sections of the SUV and help to run down the Errant Module. Please do not start by changing or disassembling any Vehicle Components until you have a more precise direction in which to go...including any Suspect PCM without first examining the Wire Bundles and Three Connectors for Damage or Wire Breaks:

Thanks MRRSM. I watched the video, twice. I'm going to start trying to isolate the problem. I'm doubtful I will figure it out, but I don't have any other options at this point. I appreciate your help very much. Enjoy your weekend!
