Hi THOEUN,

Without the TPS I wonder how the car is going to run ok. Acceleration would be a problem and high consumption as the ECU is now in backup mode. The check light would be showing.

Without the MAP sensor the idling shloud be very inconsistent, decelerating will cause the engine to stall.

When the RPM is hunting between 1000 to 3500, most probably you have a vacumn lekage somewhere.

Check for disconnected hoses, faulty PCV or leaking inlet manifold gasket.
