I recently had a front gasket replaced on my 3GMF30 for it was leaking oil.
From what I understand the injector pump was pulled to replace the gasket.
The engine runs fine but when I throttle back hard the whole way the RPM's
come down to a point where the engine just shuts down. When I try to start
it again it will not start. It doesn't even try to start. It seems like the
fuel is shut off. If I give it some throttle it will start. My idle is set
at 900 RPM's. It was suggested that I make sure the adjustment on the
"Idling Adjuster" is set correctly. With the control lever in neutral the
push-pull cable's clearance is set to 1-3mm.
Could there be an adjustment within the injector pump that is not set
correctly? I had not problems prior to the gasket replacement.
I would appreciate any help as my mechanic seems not to know what the
problem is.
