Rev's tick up and down
« on: 21 August 2007, 14:22:55 »
Hi guy's. I'm new here, and i foun your site while surfin.. I own A Opel Omega 2.0 16V X20XEV, which i bought in 1996 here in greece.

Anyway... here i am with a felling of mass lack of power and tre rev's ticking up and down having a tension to stall. This especially happens when the car spins abit even more often. Any ideas of what to do??? I chaneged my air-flow and all sensors ect.

Also, there seemes to be a proplem with the abs system. the opel dealer told me that the problem is at the abs realy's.... any ideas of what to do??

Thaks. Donald. ::)

HI Donald,

You almost certainly need to clean the breather hoses (3 rubber hoses connecting to the cam cover), the idle control valve and the throttle body.

Most important is the small hose which goes from the camcover to just below the throttle body.  Clean this (or replace ) AND clean out the metal port that it connects to below the TB.  This will likely be hard and you'll need a drill bit to clean it out - easier if you unscrew it.

The erratic idle/stalling is very common on that engine.   (Also check that all the vacuum pipes are correctly connected around the TB as a vacuum leak could also cause erratic idle.)

We need more info on the abs problem to help.

Cheers
Ian

ICV - Idle control valve

Don't replace it (yet) - just needs removing and a good clean.

TB=Throttle body

Edit: Just realised that it was the full word, not just the abbreviation you didn't understand. TB is between inlet manifold and air inlet pipe. Seen in this picture:


The outlined area is where the ICV connects to the TB (ICV removed).

In the following picture, remove the clip and small rubber hose
that is marked with the Red arrow.

Start the engine.
Feel if there is a suction on this pipe by placing your thumb on and
off it.

If you cant, then its blocked. Follow the pipe down to where it
enters the Inlet duct.

Remove the Jet it attaches to and unblock it.



This next picture shows the Idle Air Control Valve.

Remove it and soak it overnight in either Carb Cleaner or fuel in order
to clean it.




Whilst this is soaking remove and clean the 2 Black Breather pipes coming out
of your Cam Cover as shown in this Picture.
