This is Jr's van. We've swapped vans for their holiday, as our Grand Caravan is in better shape and has working A/C, and I've been doing a bit of work on theirs.
So far, I've changed out the front rotors (which got rid of the pulsation in the brake pedal), and replaced all four stabilizer-bar end links (also successful, the ride is much quieter now).
Unfortunately, a new problem has cropped up - I was driving the van this afternoon, and at one point it lost power. I wondered if my foot had slipped off the accelerator pedal, and thought no more about it. It was good the rest of the way home.
This evening, it happened again, several times. The engine would simply quit responding to throttle inputs for several seconds. At one point I pulled onto the shoulder and put the 4-ways on, waited for traffic to clear, and then pulled out again. Things were normal again, but only for a few minutes. This is a really dangerous problem - imagine trying to make a LH turn through a gap in opposing traffic, and having the throttle cut out as you start the turn.
This has not triggered the CEL or set a code yet.
I've checked a Hyundai-Kia forum, and watched a few YouTube videos - I think without exception, the symptoms are similar, but there is a CEL and associated code.
We bought the van in 2016. A couple of months later, on a long road trip, it went into limp mode. I found that disconnecting the battery would restore proper operation. Unfortunately, I can't remember if it set a code at that time. The problem got increasingly more frequent over the next week or so.
Research at the time indicated a bad TPS, which Kia recalled in the U.S. but not Canada.
I was unable to buy a TPS separately (had not discovered Rock Auto yet), but did buy a rebuilt throttle body (with TPS included).
So now nine years later I think it's the same root cause - a bad TPS.
I see that R.A. does sell the TPS separately, and am tempted to try that first. (The throttle body is considerably more expensive.)
Any thoughts on this from anyone? Thanks.
