1) if the car has been sitting around for a while (overnight, during work) when i go to start it up it takes a bit for the motor to get started, it just turns over for about 5-10 seconds then starts, but if i the car has been sitting around for about 5mins it starts up first crank of the motor.
2) when the motor is cold the engine tries to run as if it is warm (not choked) idling at 750rpm(which is its warm idling rpm) and strugling then it usually sorts itself out in a couple of minutes, then likes to idle at 900rpm even when its warm(sometimes it idles at 750rpm), im worried that the air/fuel mixture is not right when its cold and warm (like they are swapped around for some reason). Im not quite sure so any help would be greatly appreciated.
