well everyonce in a while, im starting to get confused
i have no power brakes, im sitting at the light using all my muscle to stay on the line.

why is this? its not very consistant

 

what is the car idling at?

 

probably about 900 or so

 

anyone, this would save me some leg muscles that i dont really have

its usually right after i start my car but sometimes it'll be after i went about 5-6 miles its just i donno what its all about, im pressing as hard as i can my leg is getting tired and if i stop pushing the car lurches forward

all brake pads are new

 

do you have a big cam in there or something?

 

Vacuume leak of some kind I'd guess. I think you can turn the car on, and spray carb cleaner (just a little) near your vacuume lines (especially your break booster) and see if the idle changes or stumbles. For the record I have never checked for leaks this way, just hear of someone else on this board doing it

 

You can also use a vacuum gauge on the brake booster line, check the the plastic fitting going into the booster.
