First, my google fu is weak and I'm not finding similar enough issues. Car is a 03 rio cinco 1.6 auto 79k miles. Runs good cold though idle fluctuates for first few seconds. When warm it runs terrible. No codes though. Won't idle and won't accelerate well. Replaced wires and coil due to arcing. Haven't checked plugs yet. Really feels like an ignition issue. Like its not advancing or the spark is being retarded. It will hold rpm fine. But any load more than very light acceleration will cause it to fall on its face. It also shifts odd but it could be due to perceived load on engine. A little history, vehicle smacked a deer less than a year ago. I got it dirt cheap and it wasn't that bad of a hit. Thanks for any ideas.
