Poor idling

[drew.h]

My Chimera is idling a little rough. When just sat there you can hear it searching. Idling along can be a bit bumpy. As soon as I add throttle it smooths out.

I have had the idle control valve off and cleaned it, but it didn't make any difference. Is there any way of testing the valve to see if it is working?

Just remove from plenum chamber and then reconnect to plug.
Turn on ignition and see if the cone at the end moves then turn off the ignition and it should then move again to it's park position.
Cheers.

I'm a but slow getting jobs done on the Chimera at the moment, but had a chance to look at the idle valve yesterday. When removed from the housing and I turn on the ignition nothing happened, as I turned off the ignition it buzzed.

I managed to figure out that the it was seized. Some WD40 and BFnI freed it off. If I turn the ignition on still nothing happened. If I wind it out by hand then turn the ignition off it it retracts. Does this sound like its working?

Went out to collect my new headlight reflector, on the way the car stopped not firing on all 8. Cause was the two plug leads to the rear of the engine, one was lose and the other had come off and melted to the exhaust manifold. These where new leads I only fitted yesterday, they don't grip to the plugs as good as the old ones and they where held tight out of the way of the manifold, which probably caused them to spring off. Just made a heat shield to hold the plug lead away from the exhaust, I'll see if it works tomorrow.

Yes sounds like it is working.
I may be wrong but the engine might have to be started to make the valve come out.
However if it is retracting it sounds like you have fixed it.
Cheers.
