Brakes causing miss and stall?
« on: July 04, 2013, 09:57:38 pm »
I just recently put a crate engine in my 1985 GMC K10 Sierra Classic. It sat for a few months in a field. Since I've had it running when I press the brake pedal all the way I here an air leak under the dash and the engine will miss and stall. Any suggestions?

Replace the power brake booster.  Make sure the vacuum hose supplying the booster is in good shape.  The "air leak" is a ruptured diaphragm in the booster.

You may try a new check valve.....its easy and cheap before you have to replace the whole booster.  Its the plastic piece in the front of the booster where the vacuum line plugs into.
