as the title says i have a servo problem in my firestorm i took it out 2 days ago for a bit of bashing did a few jumps and the place was really dusty so as you can imagine my car was covered with dust so after a days bashing i thought it could do with a good clean so i sprayed some muck-off on the chassis to give it a good clean and after i cleaned the car my servo was acting rather odd the thorottle servo was stuttering when put some throttle on i checked the batterys and they were fine i've opened up the servo and to me there wasn't a clear indication that it was f****d if you could please help me will put some pics of servo if needed.
