SOURCE: high revs

being a fuel injected engine , there are many reasons this could be happening.
from the top , lets check the Manifold Absolute Pressure (M.A.P.) sensor , as it is easiest.
Find the MAP sensor , it has a couple a wires and a vacuum tube going to it and is on the firewall or fender support under the bonnet.
Disconnect the wire harness from it (small plug with wires).
If the engines RPMs drop to normal , replace the MAP sensor.

SOURCE: Car rev up and down at startup, also car jerks at release of gas

This sounds like a vacuum control problem. Since part of the problem is when the engine is cold; a thermal switch is venting vacuum until the engine warms up enough to shut down the thermal switch, thus restoring a steady idle. Vacuum can be affecting high rpms while running too. You could have a misrouted EGR vacuum line opening the valve at the wrong time. There are sometimes hose routing decals on the radiator shroud or under the hood. These can be visibly checked.

SOURCE: I have an '86 951. It will not rev above 1600rpm.

clean out the fuel pressure regulator with carb cleaner spray(a good clean ), then spray dry lube into it. This part is located on the fuel rail, sits at the front of it, has three connections/holes and fuel comes out momentarily after disconnection.

Engine revs up down while in idle


If its been without the line for over a year, I Highly doubt it. Look into IAC valve. Most are installed with 2 screws, easy to adjust. Idle Air Control Valve. Look that up, for a start.

Revving problem


Check the fuel pressure. Could also be clogged injectors-assuming it is fuel injected-you didn't say what year. Also check for a big air or vacuum leak.

Vw polo maintains engine revs when foot is off the accelerator.


You need to check the cable the runs from the gas pedal to the engine, it might be rusty and need some drops of penetrating oil at the point it meets with the engine accelerator valve.

Over revving


I don't know the year but it could be a defective IAC solenoid. If its an older truck then it could be a throttle cable.
