What causes hesitation on acceleration in a 2001 Kia Sephia? I had the converters worked on at a garage, but it still giving me the same hesitation.
When I accelerate after shifting to next gear sometimes, the car will seem like it
hesitates briefly. When the check engine light was on, I got it checked and it was the
converters. I had the lower one removed and had the higher one de-gutted...I'm not
sure if they took this one out though. But in any case, it was all supposed to be
"fixed". Yet I still have the same hesitation when I drive...and every once in a while, it
will hesitate in idle. What gives?
