New problem, with codes
Coming back from NAPA just now, truck started to cut out. SES light on. Got it home and found P1316 and P0344 codes stored. Truck has an intermittent miss at idle now.

P1316 - IDM Injector Circuit (Injector Driver Module)
P0344 - CMP (Camshaft Position Sensor) Sensor Performance
Since you replaced it, and it improved, perhaps you have it repaired.
Hook a scope to it and you should see nice square top-end pulse frequency's.
The Grey one is better than the one that was in it.

VC gaskets as well? You might look up top and see if it's all tight there, but I wouldn't pop any VCs yet. The IDM DTC code might have been lurking in the shadows from long ago, and the CPS SES pop made you find it. The IDM could be nothing more than a fail-to-sync some time back. Roll and watch, my friend.

My mileage has improved greatly since the cps change but I still have an intermittent miss at idle once it warms up. Off idle, its fine. When I do a buzz test with AE will it give me the idm codes? Which is the best cps to run in these things now?

The black is the one to get, also as rare as rocking horse poop. Soooooo, after all the money I've spent on this I have to deal with a miss at idle? This is going to bug me to no end......
