A: Yes, I have. As a matter of fact, I keep one in each of my vehicles, except the Harley. Many newer cars come standard with an inflator that you plug into the power outlet (formerly known as the cigarette lighter socket). Along with the inflator is a can of puncture sealer. This duo replaces the spare tire which took up space and added weight. You can find them in auto parts stores and I would suggest getting one to keep on hand.
A: Because the air we breathe is almost 80 percent nitrogen, spending $20 for more seems unnecessary to me. But if you choose to replace the air with nitrogen (not nitrous), you can leave it in all year. But be cautioned that should your tires need some future inflation, you should probably seek out a shop that offers nitrogen because it is not available at your local 7-Eleven.
A: Because the car is running well, I suspect that the engine control system is getting some bad information. The system relies on inputs from numerous sensors and the accelerator pedal sensor is one. But I am not ruling out something else. If a sensor, its wiring or connections have a problem, the check engine light will be triggered, even if it only happens occasionally.
A: Please let your friend know that this is not the case. If it were, cars bought in Florida would not run properly in Minnesota and vice-versa. Besides, could you imagine the cost of production for automakers and, ultimately, buyers?
