Ok I just checked ignition timing. And something weird is happening.

ItÆs warmed up, I disconnected and plugged the egr and canister lines. And shined the timing light on the balancer.

And when itÆs idling by itself (IÆm not pushing on the throttle) itÆs really retarded (mark on balancer is to the right). About 2ö or so.

But the instant you add abit of throttle it jumps back to the ô0ö mark where it should be. Then if you let off the throttle it either tries to die or again idles down to 850 or 900 RPM and shows allot of retard.

And it Instantly jumps to the "0" mark. Not a slow movement, when throttle is added.

Could this be a problem with the "distributor advance mechanism" in the distributor? <img src="/forums/images/graemlins/confused.gif" alt="" />
