I have had a problem for almost a year where when the weather is really hot or cold and I use the defroster or a/c my car starts to idle extremely low and has stalled. It has also not started and needs a few times to start. I have had it checked numerous times and no one can pinpoint the actual problem. I do not want to spend so much money on something that is not a definite problem. Some have said it's the sensors that need to be replaced and some have said other things. Any help would be greatly appreciated.

My car stated having this issue about 2 weeks ago, Took my car to Honda immediately and was told it was bad gas, since I had a full tank, I would have to drive the gas out replace with premium, and add some octain booster, and to call them back once I had driven the gas out and replaced with prem gas. It took a week for me to run the gas out replaced with prem gas, and my RPMs still ramp heavy, the AC drags my engine so hard that if idle at a stop sign or traffic light the car will shut off. So I'm stuck in hot Florida riding my two babies around with no AC. When in reverse, drive I have to push immediately on the gas or my car will hesitate. I was then told that my computer needed to be updated with new software, but per Honda I had the latest software and there is nothing they could do, as they can't find what the problem is. My spark plugs are good, I do not have any wires, no distributor cap, Honda doesn't no what to do now. It was suggested I get a new car while the check engine light was still off.
