idea please
 

hi. so i have a 1985 gsl-se the body is very good with new paint job. i got some new shocks and springs for it. so now i wanna do some stuff to give it more power. any idea on what i should do? also if anyone has some parts for sale let me know. oh yeah another thing is its idealing at 3k, it seems to me that the throttle line thing is getting stuck when i press on the pedal but when i go to the engine and move it back down its fine til i step on the pedal again. any idea what i can do?

Check the torque on the nut/bolt, and lubricate for starters.
