you brought this predicament to yourself, as far as i remember warning is placed in engine room of santro not to do any such thing.
Now whats done is done, try drying out all electrical parts effected (start with Bismillah), starting from the coils, locate the ignition coil bolted on the right side on engine head, remove the grip and dry out using blower or hair dryer carefully, also remove ignition wires one by one and dry them out. also check the other end of cable connected to plug for moisture, if found dry it out.
next step is remove grips from the sensors ( IACS and TPS) on the throttle body and dry them out.
i hope this issue shall be resolved, if so then donot get brave, rather do proper tauba and make resolution not to repeat such sins again.
