my 73 340 duster has developed a small but aggrevating problem. car idles fine when first started. as it warms up, when you approach a stop light idle goes up. when I blip the pedal it drops to normal.possible vacume leak maybe? the guy I bought the car from said something about the brake booster having a vac leak? he said he had this happen to him and that's what it was. I just wonder what the booster would have to do with an idle problem? I have an eddy 1407 carb. brakes are fine. other owner said to try wd 40 on the throttle rod , possibly sticking a bit. did nothing. maybe idle air screws need adjusting? any ideas ? I am no pro mechanic, just another roofing contactor. cars a 4 speed
