Can only rev engine up to 4000 RPM then stops will idle fine?

Check the shop manual for your car. Every car has a limit as to the highest rpm the engine will go before it stops. It is a safety feature. 4,000 rpm sounds a little low, but it could be correct. Normally, it is higher. If it is higher, you either have computer problems or a broken wire or a wire with a little insulation missing.
