why did the ecu light come on and has now gone out 3 Answers

My 2014 Hyundai Tucson has idled poorly since purchased new. It has been in the shop multiple times and until the visit a few weeks ago nothing was done. The throttle body was cleaned on the last visit and that has helped but it is getting back to its old self slowly. I have the car parked at my office from 6:00 a.m. to 5:00 p.m. each day and as soon as I get in the car and make it to the first traffic light it is idling down really hard like it is about to turn off. It has also lost power when crossing intersections and skips or whatever it is doing going down the road. I don't understand why a car that was purchased in June of 2014 and is not even a year old would need the throttle body cleaned. Anyone out there experiencing these problems? The cloth seats in this car are also horrible and become stained by rain water while putting groceries in if it is raining. Thank God I purchased the warranty on the seats. Thanks! 5 Answers

Ok i had bought a 2004 Hyundai tucson v6 and it had ran ok for a few months but when i bought it i noticed the engine light is on so i took it to auto zone so they can read the codes for me and they said i needed 2 O2 sensors and 1,3,and5 was misfiring. But it still ran fine ,so i said don't fix it if its not broken.lol. but ishould of fixed it because now it is running bad. It starts and everything but when you put it in gear it wants to die out and when pushing gas pedal it runs rough or comes close to dieing out . So i checked the sensor the messures the air and gas , put it on my meter like it's says on YouTube and it was fine. But really stuck on what to do ,don't have much money to go buy all kinds of parts and it doesn't fix the problem. so if there is any body out there that might know what is going on please help me figure this crap out . Thank you so much and God bless everyone 2 Answers
