Error Code.

[Daboss]

Hey forum whats up? Need you guys help again, I checked my ecu for error codes tonight and i got error code 21. Now I checked on the code and it came up as an error code for the ignition signal. What does that mean and what can or must I do to fix it? I have a 95 r33 gts-t. All help is appreciated. Thanks in advance.

It is ignition primary signal failure, which means one of the coils has missfired the fun part is finding which one,

Q: is, does the car run fine, or have you just got the error code?
