Last night pulled codes 16, 18, 67, 87, as it cut off at idle 4 times on the drive home, after I was off the highway, no problems when my foot was on the gas, no problems on the 3/4 mile home from gas station.

Pulled the battery cable overnight, which appears to have been a mistake, won't start this morning, code 18. With my foot on the floor it catches and revs way up so I immediately get foot off pedal and it dies.

WTF? SPOUT? A switch in the shifter?

Thanks.

Starts with spout out.

now that to cleared the KAM, base idle need to be relearned/reset, once that is done then you can troubleshoot for the original problem

It runs with spout out, but won't catch with spout in, surging slightly at idle.

What do I do? Get a new spout plug?

Now it starts and runs w/ spout in, I cleaned spout plug pins, they didn't LOOK dirty...
It cut off after 2 minutes, now it's running at about the same uneasy idle as before this started.
How many minutes of running and/or key on-off cycles until I can meaningfully pull codes?
Thanks.

like I said you need to relearn idle and then go drive the car some so adaptive memory can relearn drivibility and idle......listen!!!!!!! after that we can troubleshoot the issue if it's a stall issue while driving, could be ignition related and probs with stator and tfi are common

Thanks for the advice. Got it running, and drove with the radio off so I could hear the engine, since that must be what "......listen!!!!!!!" meant.
Drove 20 miles mostly highway, and 4 hours later drove it 20 miles back. No issues so far.
Is it too soon to pull codes yet?
Thanks again.

you can pull codes any time

Put another 40 miles on it, I get 18c and 67o. Runs OK.
