Issues with cam upgrade

[Dowatt]

Hi, I have a 2010 Mustang GT 4.6 V 5 spd. At 142k my engine started misfiring, after further investigation we determined 2 cam lobes were wiped on bank 1. At this point I decided to upgrade to Ford performance Hot Rod cams. We replaced cams, rocker arms, lash adjusters, oil pump, timing chains, chain tensioners, VCT solenoids, phasers and 3.73 gears. I also purchased a revX tuner and custom tune. First failure, chain tensioner bank 1 failed (acted like cam had jumped time) tore engine down and replaced. Current failure, when I run the AC I get a erratic idle and get the CEL. Fault codes are P0021/P0022/p0011. I reset codes and engine runs good till AC is on at idle, I tried running the AC again to see if problem would returned and got the CEL again but this time I only get the P0021 fault code. I'm thinking the VCT solenoids are possibly contaminated from engine break in metal? Or just a faulty VCT solenoid? The chain tensioner that collapsed was purchased from Rock Auto along with the VCT solenoids (Cloyes brand). Worst people to deal with ever! I decided to purchase 2 new VCT solenoids (Ford Motorcraft) and they arrive this weekend. Anyone else have similar issues?

First thing I would do is remove and discard all the valve train parts you installed that do not say Ford on them. Chains, sprockets, tensioners, phasers and anything else of unknown quality. That is the heart of the engine and no place to use discount parts.

Yes, it's a Bama tune.

How do I do a Idle relearn?

Anyone else have similar issues?

Update:
Bama suggested I wipe the KRAM and drive about 20 miles to relearn. After about 20-30 miles engine smoothed out and ran like a dream. Got home tried the relearn on the AC and it worked like a charm. Idle smoothed out. I drive 90 miles a day to work and back, hopefully I won’t have more issues!
