    Its been about a year since I cleaned the throttle body but I rarely drive it, maybe 50 miles a week. I'll do them both. Thank you.

    Surging idle

    Just discoloration from exaust, no build up on the passages or in the valve. Was looking towards the IAC . My other trucks are so old they don't have an EGR so I really appreciate the advice.

    Surging idle

    My 2000 yukon denali starys right up but surges and stumbles until it warms. Occasionally it doesn't want to take throttle from a stop, doesn't die, but its as if the thottle and peddle arent connected for a few second and then is fine. I cleaned the EGR valve and it is marginally better. Only...

    Freewheeling

    Ok folks got one I need educated on. Been a long tome since I've done my own work, so I've never come across this. Picked up a 2000 denali that runs pretty good and figured I'd do the work myself starting with the brakes. Put the whole thing up on stands for ease and proceeded to remove the rear...

    Radiator pressure

    I've never seen anything like it rither. New 4row, cap that came with it, freeze plug was replaced prior. "Shot out" like an over boiling studibaker. No one else touches it. Since then, I topped it off, put dye in it and drove it at temp for 20 or so miles, no problems. Must havr been gremlins...
