Adjust Mehran RPM by Throttle bolt

[hotcoder]

My Mehran's Throttle nut/bolt adjustment is disturbed by a mechanic and the RPM is set too high because once I told him the engine and car was shaking (Although it was due to bad mounting).
How can I adjust the throttle nut/bolt and engine's RPM?

find any other mehran, with throlyle stop screw at stock position, carefully count the thread on that and adjust on ur car..

else connect a OBD tool to adjust throttle stop screw according to TPS value...u can use multimeter with aligator grips to measure voltage at closed and wot position and adjust accordingly...

before doing it kick yr mechanic for making such mess and ask him to get u an unaltered throttle body
