its an 89 sierra changed head gasket.it ran fine for 2 days now any left hand turn will flick the handbrake light on and it wont idle properly!it sits at 2k sometimes 500 but worse of all it really surges at idle(im sure the people next to me at lights thought i wanted a race)the car drives well under load.any help would be appreciated thanks |

check your brake fluid if its low it will make the light come on as a warning the surging sounds like a vaccuum leak |

Also check handbrake switch, more likely low brake fluid but |

the surging sounds like a vaccuum leak I thought the handbrake was cable activated, no fluid. |

Oh ok, never knew that one. I alawys thought it was a magic switch like the one that shuts off the fridge light when the door is closed. |

you may also have a leak around a gasket get a squirty bottle of water and while its running spray it over everything if it has a vac leak it will get drawn in and the revs will drop. |

You might like to have a quick look over your brakes to find out where to fluid has gone, leaking wheel cylinders or worn out front pads, then bleed the fluid through with some new stuff. Brake fluid is often over looked but still quite important. |
