p219a
Chevy express 4500 6.0L 2 wd Automatic 72k miles
When driving in Altitude the p219a code has shown up. Below 5k feet it never shows up. When the code is reset it is gone for the rest of the trip. The engine is also running a little lean -17% on the long term fuel trim and will drop back to -8%. So I am running lean. Are these within limits? should I be concerned at all? Everything is running just fine!

Everytime I took that car up in the hills and got up to around 4000 ft or so, it would flat out die. (they dont call them found on road dead for nothing). If I waited about half an hour, it would fire up and run okay going higher up, and even coming back down to the lower 175 ft> sea level ground where I lived.Took me a while to determine that the ignition module was defective and that many of them were defective, not just my car. Wasn't long after that I sold it and never looked back again. Bought a Camaro and ran the tires off that old beast.
F-O-R-D? Never again!

Likely a MAF or Oxy sensor problem. At least its still running good, so not really a big issue, even with the trim. When I was much younger, I made the mistake of buying a fuel-injected 5.0 liter Mustang.
