Cleared all codes this weekend, just to be sure nothing was caused by the unplugged MAF. Removed the IAC and cleaned it and the TB passages, cleaned the MAF, changed air filter, and coolant temperature sender. Tested fuel pressure, 48 psi running, 52 psi regulator vacuum un plugged. Checked the resistance of the air charge sensor seems good 2.6 K-ohm.
Same problem, when first started "cold" runs fine @ high idle for 1 minute, then idle drops to the point of stalling, if I keep it running by feathering the throttle it clears up in 3 minutes and runs fine, until next cold start. No SES light set.
