My 2001 hyundai elantra (automatic) some times loss power when accelerating, at the same time the check engine light turns on. When his happen i find myself trouble going up hills, any idea what it could be? I have not taken it to the shop.
The check engine light usually comes on when there is a faulty sensor. or circuit. Sounds like you may have a faulty throttle position sensor. It would be best to have engine codes read to pinpoint exact problem area. Many part stores do this for free.
