Question about 2006 Hyundai Tucson
Does the car do this every time, or just if you go though all the gears into high locckup and then slow down? Do you notice the car shifting down as you slow down? Is the check engine light on as you drive the car? does it go out some times or is it alwayson? Can you start the car and put it in gear and the engine seems to run fine? while still sitting there can you then turn on the air conditioning and it still run fine , or does it try to stall or stall even. Have all the fluild levels been checked? Whole pulling out and acellerating does the car pull out smartly or is it worset than it used to be? Did you just get a new battery or have other service work done that may have had to have the battery disconnected or the battery go dead for any reason? So now what to do? First if the check engine light has been coming on or is staying on that needs to be checked first. An auto parts store can test for codes and give you an idea where to go next. Not knowing those cdes now won't let me tell what to do right now. If the battery has had issues like I spoke of then the engine may have to relearn the idel in all modes. ( It idels sometimes, right? ) The procedure is to start the car and hold a high idel with the gas pedal ( don't race it or pump it ) for two minutes. ( that seems like forever when your just waiting ) After this warm up and the engine still going faster than idel turn everything on. Air conditioner brakes and still hoding it somewhat fast hold the break good and put it in drive. now slowly let off the gas and let the computer try to set the idel. It knows this meathod and will try to set a new idel. once ideling in gear, put it back in park and turn things off themn shut it off. wait a minute and restsart the car and drive it normally. if it doesn't stall any more your done. If the car doesn't warm up all the way it'll stall too If it has a temp gauge and it doesn't come up to normal fairly quickly it'll stall and use lots or gas. If someone has removed the therostate or the car has gotten real hot and now the stat doesn't keep the right temp. it'll do this. Overcooling is just as bad as overheating so this must be fixed and in some situations the check engine light will come on and the code for not hitting operating temperture will be stored. If this is the case the car may run OK when first started cold but fail the same test a few minutes after starting. Try these things and then tell me what you find out. Low coolant low oil oil that hasn't been changed, and overheating of the engine or the transmission, to a dirtly raditor ( wher the air goes though) full of bugs or dirt. will all cause this problem.
