I have a 94 pretaco 22re, when I am stopped and I rest my foot on the break my idle dips occasionly. It took me a while to find out what causes it, now I need to know why and what can I do to fix the problem.

sounds normal to me... the brake booster is stealing some air. how low does it dip?

Is it the A/C compressor cycling on? See if does it with the a/c off.

thanks, I will try shutting my ac off,

it dips a little prolly 100 rpm

wow thats way too low. check the iac valve? clean the trottlebody? hit it with some carb cleaner (worth a shot).

Do you mean it dips down to 100 or 100 lower than normal?
