Engine Stalling/ losing power momentarily


2000 Hyundai Elantra Stanard Shift, 134000KM
Since I got the car in 2000, the car will be driving along fine at high speeds and then feel like all the sudden the power is gone, and then instantly it starts up again - it doesn't acutally stall and the engine light never comes on but it feels like the car kind of misses a beat or something. I had the car into the dealer two days ago and took the mechanic on a long drive to see if he could get the car to do it - (it is happening with more frequency lately) The mechanic was kind of stumped - but said he would try to adjust the throttle on it. The next day, I drove a few errands and noticed the car was bucking and losing power even at low speeds - and now it kind of felt like it was going to stall too - engine light came on - took it back to dealer and they said it is a sensor - could it have anything to do with the fact that the throttle was adjusted? If it is a sensor - how long to put a new one in? I suddenly don't trust my dealer so much but can't find a site that tells me how long the repair should take so that I have some sort of idea.
they said it is a sensor -

Do you
have the same problem?

Nice story but I can't help with out the code that is showing. I would say the adjustment of the throttle was not where to start. You are stating that if I held the throttle constant at say 3000 rpm it would run fine but falter once in awhile. That could be a electrical sensor failing yes. Ie cam or crankshaft sensor or it could be a fuel delivery problem such as a filter. The code is imperative.

Was this
