Hello once agin I have some questions. The issue I am having seems to be the engine cuts off/out goes from 2000 rpm to 1000 rpm at speeds of 60-70 mph. If I step on the accelerator pedel the engine fires back up with out skipping a beat! Runs great! No Check engine light comes on. So I guess I would like to know what does not turn on the check engine light that might be causing my issue? I am thiking fuel like fuel filter or a throttel sensor ( but would the throttle sensor turn on the check engine light?). Any Ideas from yo folks.

Thanks in advance.
