2001 Daewoo Lanos Sport Problems

[rnccen]

I have a 2001 Daewoo Lanos Sport 1.6L which I am at a loss to what is wrong...

I began to experience very high idle at park/neutral then engine racing at traffic lights, then it went to shuddering / stalling and loss of acceleration with hesitation. I replaced plugs / wires...CEL came on...Auto zone said general mis-fire.

The car then started fine and when put into drive / reverse it dies despite pushing pedal down to floor...back to neutral or park engine can be kept somewhat started by fluttering the gas pedal.

I took a chance and replaced the fuel pump and fuel filter...most of the sensors have been replaced (waiting for crankshaft position sensor to arrive) because I borrowed a friends OB2 which gave a GM code that indicated the crank shaft position sensor was an issue...no other codes...the misfire code has not come back up.

I don't know if the Crank Shaft Position Sensor will prevent a vehicle from running properly...also once it is replaced I read about doing a TEC Test or Relearn?

Can anyone provide any input or insight...I need my car running as it is my only car.

Thanks

Paul

did you try to clean the IAC and do an idle learn?
