ok. the car idles fine for a little bit... say 30sec..
and the idel just slowly drops and stays areound 200rpm.. and shakes around.
it sill sit at 200rpma nd nearly stall then jump back up to 600rpm then go back to 200 and stay there for a while..
i ahve checked pin 21 on the ecu and it only measures .007volts, however i checked the continuity of the solenoid and it is continuous.
the isc is a little carbonised but i dont think it would be so mcuh as to cause this problem...
i have not removed hte throttle body.. as i am having trouble getting to the bottom bolt closest to engine block...
thanks in advance.
