Is your check engine light coming on? I am sure it is. If so, you need a diagnostic run on the computer to pull the engine codes and go from there. it's usually some electrical part that pertains to the idle that needs replacing..........could be one of many many things making it do that. Take vehicle to shop that can diagnose it and repair the problem. go to the dealer if you dont' know of a really good diagnostic shop, as computer diagnosis is very tricky.... one part gone bad can trigger other parts to act up and it's difficult at times to accurately diagnose the correct part to replace to make everything kosher.

Hyundia sonata glx auto 1997cc. 1996 model year. approx 53000 miles Engin starts and reves up to about 2000 + rpm then after a short time may be a miniut drops back to 900 to 1000 but surges to 1500 every...

the surge is caused by a high idle situation where the computer pulls it down but it goes back up again,hence the surge.Hopefully it is just pure bad timing that it played up after the brakes being done as nothing needs to be disturbed by it.One came into my shop like this and the idle air bleed had been tampered with.this is located on the throttle body(this is where your accelerator cable goes to).It should have a black rubber plug in it about the diameter of an aaa or aa battery end.remove this(some are already missing),inside this is a flat screw type head.Using the right size screwdriver slowly turn this clockwise while the engine is running in park.You should only have to turn this 1/2 to 1 turn in to alter the idlespeed.if no change or it slows then surges again,we will have to check some other areas.Also check your coolant level in your radiator,as these have 2 small hoses that feed coolant through the throttle body,this can give same symptons.There are a few other things to check but at this stage just check these 2 items and of course look for any hoses or sensor plugs that are not on,or any loud hissing of air escaping anywhere.Hope this helps.

High Reving sound when gas is pressed

Check your transmission fluid level with the engine running and your shifter in Park. When was the last time you had your fluid and filter changed? Could be a plugged filter.

Engine revs high when started,andrevs surge up and down even when hot as if its being reved on and off,also where are cambelt marks for timing belt 1.2 16v w reg 2000 model

Does this have a self diagnosing emission system, like the USA markets OBD 2 system? we don't have Fiat's here since early 80's, this sounds like a Throttle position sensor issue or idle speed control valve problem, if there are trouble codes stored in the control module's memory please provide them to me along with the definitions, but check the TPS and Idle speed control first.
