Sir,
I have this code P0505 ; Idle System Malfunction with the Check Engine Light on.

1) What should I do to fix this problem?

2) Will this problem if not fix affect drivability?

Diagnostic is only available using a DRB capable scan tool. If left unfixed, you will have either rough or intermittent idle, no fuel economy, and eventual ECM damage, or worse, engine damage from rough idle and lean/rich condition.
