Is it a manual or automatic?

Auto....I was just told that I need to do spark plugs, wires, and valve cover gasket. The check engine light just came on today.

Those could definitely cause it.

It's going in tomorrow for that and getting the timing belt, and water pump done also.

huh mine is doing the same thing, my mechanic said it was not due for a tune up for several thousand miles to reccomended service even, but I have also heard it gets carbonded up in the throttle body, heard spraying some o2 sensor and cat safe carb cleaner does the trick will have to try it.

2000 Montero Sport is doing the same thing. What is the real solution?

it could be the crankshaft pully bolt. I had this issue and come to find out The Montero has a recall on that bolt. the bolt will work its way loose causing the belts to be loose & sputter. they will replace it for free with a better bolt.
