i have a 1982 307 olds v8 in a 87 cutlass and when its in park i can rev the car up and it idles down right away like any normal car but when i put it in drive and apply the brake and give it a shot of gas it doesnt wanna idle down like it should it just keeps idling high like someone is pushing on the throttle or sumthing, its not the throttle cable getting caught or anything, any idea's?

here's a longshot... check the vacuum pots on the carb. When you put it in gear the idle drops making less vacuum. If one of the pots has a leaking diaphragm it could be letting the idle return pot not retract.
