Check Engine Light illumination—combined with a lack of power or a stumble on acceleration—may be caused by the throttle position switch (TPS). Kia released an improved part which should correct this concern.

My 2006 Kia Sportage started stalling when I would come to a stop light/sign. It would start right back up but I was afraid that it might not. I took to the Kia dealer to troubleshoot. Of course it didn't happen for them. It continued to happen so I took it back and told them to figure it out. 2 days later, they replaced the throttle position switch and the problem seems to be fixed (4 days now without the problem). Cost for part was minimal - $41.00 but labor was $160. Total bill was $213.00 but I'm glad to pay it if the problem is fixed. My car only has 31,100 miles on it and otherwise, its been a great car.
lack of power, would not accelerate on triptronic mode.
on automatic it was taking a long time to reach 45 MPH, check engine light came on.
something related to the throttle had to be replaced.
Starts up but if I hit a bump it acts like its going to stall, then after a couple of miles my kia shuts off. If I jiggle the TPS pigtail it will start back up and then if I use the air you hear a lot of ticking sound then it stalls. You hear the clicking sound coming from the TPS.
