Question rough idle and surging

My 2001 when first started up will have a rough idle. When put in drive will surge or "buck" for a short distant then it will stop doing the surging. It also feels to me the idle is abit faster than before. I'm thinking start with a tune up. I have 118,000 miles and a automatic. Any suggestions before I head out to the shop to prevent getting screwed.

well you did not say if the timiong belt has been changed so if it has NOT you are over due it is a pain and expensive but it has to be done what you are describing kind of sounds like the cam sensor that is easy and pretty cheap

So many, many things this could be. Vac line, one of the sensor, belt, plugs, plug wires, fuel filter, air filter, etc. ad nauseum...

Need to know a bit more info. Have you tried the 'key dance' to see if your tossing any codes? If so, post them here. If you have not had your belt replaced, you need to do so and have the water pump replaced at the same time (saves money in the long run). If you have, then look towards a fouled plug, or maybe a bad plug wire. Whens the last time you had the oil changed? Is your car a turbo or NA? If turbo, are you running 93 octane fuel? Whens the last time your tranny was serviced?

Just way too many questions to give you a simple answer.
