My Tucson seems to hesitate when I tromp on the gas and want to go quick. When I mentioned it to the dealership they said they could reset the computer for free.
He said it was something to do with the computer memorizing my habits...except it had this habit when I got it. I find it annoying that it doesn't respond as quick as I'd like it to.
What does this procedure entail? They said they would do it at my next oil change. Isn't this something I can do myself?
What the dealer is referring to is your ECU which manages the air/fuel flow management. All you have to do to reset it is disconnect your battery for 15-20 minutes (step on brake pedal once elminate any remaining juice in the system), then reconnect. Once the reconnected the ECU is reset. As you begin to drive again the ECU interprets how the engine is running at your current elevation and driving conditions, and begins to tune itself by adjusting air/fuel mixture, etc. to find a common ground between engine efficiency and gas mileage. My Elantra did the same thing, had a hesitation around 3800 rpm. Reset the ECU and it was fixed. Only temporarily though until Hyundai actually released a TSB to reprogram the ECU to eliminate the hesitation alltogether. Maybe they will do the same for the Tucson if it is the same sort of problem.
