Took the wife's 98 zetec atx Mystique in a couple of weeks ago and a vacuum line was replaced, along with the water pump, serp belt, and temp sensor unit. After getting it back, when the engine was dead cold, giving it a little gas made it miss, and almost stall (as if you turned teh damn engine off), but got better when warm. When warm it would do it a little, but not as much if you gave it about 1/4 throttle. It really seems to accelerate slower (both of us notice it). Since it happened at the time it was fixed, I took it back thinking maybe the comp needed a reset, but not sure. They told me it was the Variable Valve Cam Timing sticking and it should work out, but not for sure.. and if didn't or got worse, bring it back. Anyone else have anything like this happen???
