Freddie, How warm is "completely warm?" If I just started my car and drove, I also had power loss in the first minute or so. This was well before complete warm-up to the 1/4 mark on the gauge. I did not have the racing/backfiring you describe. Turned out my air filter was clogged. The problem is virtually gone now that I replaced it. Sounds like yours might be something else. More technical folks will have some thoughts and diagnostic approaches. I'm a novice, but I think some hunting is normal during the warm-up period. I sometimes have a little hunt at idle even when warm, probably because I could use a new O2 sensor (how is yours?) or some minor adjustments. How dramatic are your RPM swings? I believe there are notes in the tech section on how to test your O2 sensor and general notes on idle problems (such as fast idle). You might take a look. The message board "Search" function is also quite useful to find answers in old posts. I believe there are detailed notes on optimizing your idle with the O2 sensor disconnected, then reconnected following adjustment, buried in old messages. Good luck!
