Try servicing the air filter.
Most common culprit in surging is a dirty/clogged air filter.

Every time you engage the clutch, the clutch disengages from the transmission/engine. Which in term engine revs up, until you disengage the clutch.
The most common cause of engine surging (rev up and down) is a dirty air filter.
Because that's how an engine runs. it can only ever rev up if you give it gas. no gas, no revs. more gas, more revs
replace the Air Idle Control Valve for starters
The most comon cause of an engine that keeps revving up and down (aka surging) is a dirty air filter.
because the engine turnes at diffrent speeds ie. tick-over is about 1.5k revs where as speeding down the road is at 5k revs the faster the engine turns the more the pressure builds up
Turn the throttle, revs go up. Let to, revs go down.
Gear changes are determined after how fast the engine is turning. For each gear there are set limits for which engine revs that are allowed. if the revs go high, the transmission changes up a gear, if the gears go low it drops down a gear.
Yes it does, mine has exactly the same problem, can be the MAF sensor, fuel pump problems or the idle sensor. just changed the MAF on mine saw some improvements but still revs up and down occasionaly
