What did you think of the first file sound NMK?? Maybe same problem without the squeal??
Hmmmm....so maybe not enough starter pep (right at max compression) is the problem right from new.
They never did replace the starter. They replaced the relay and then adjusted valves.

Thanks a million NMK. You could very well be right.

You da man...(:

This starting problem is still in effect. It has a new sound. I have attached the old and the new files. Anyone care to
have a listen and see what you think. Dealership can't seem to pinpoint the problem.

Idle fast was was caused by flywheel key broken as seen in the Quote

Thanks

My ZForce 500 is now in the shop for the second time. (800 KM)
First time was strain when starting. (tension at a certain point of engine rotation). Adjusted valve clearance.
Appears ok, but something still not normal in my mind. I'm thinking there should be a steady rotation pace until
it catches and runs. But pretty much every time there's an interruption where everything falls apart with
a clang sound and then picks right back up and continues rotating normally until start. (I am not thinking a loose connection.
The pattern is too consistent).

This time it fast idles (even when fully warmed up). Can't shift in gear.
They changed the Throttle Body....not fixed. Now they have the computer on order.

Any comments??

Hey NMK....this download worked fine for me.....yeah!

You may remember our last stint a little while back for the UForce 500...ha

I am thinking the high torque at a certain point in starting rotation problem I had when new
caused the shear. The starter would actually stall and finally continue if key held.

This turned out to be a sheared flywheel key.

My Zforce 500 has it under the steering column. The little plastic case can be removed by pushing upwards.
