Hey all,
New to the forum but have been a long time lurker.
Have been faced with a strange problem on my 1999 R34 GT. Sometimes when ive been starting the car the MIL (engine check light) comes on and the car tends to shake a bit more than normal, noticing this i realised that it runs on 5 cylinders instead of 6 when it lights up.
However the light will only light up once or twice a week and the car runs fine (all 6 cylinders working) whenever I happen to start the car and the light does not show up.
I managed to get the ECU scanned recently when it lit up and the error code 21: Ignition Signal Circut came up.
Is it likely that this is due to a faulty coilpack or related to the crank angle sensor?
Has anyone else had a problem similar to this?
cheers
matt
