    I have a 95 Tahoe with 240,000 miles... You just can't kill them...

    First thing to do is pull the engine codes. You can do this by blinking them out. Looking at the diagnostics connector and the key in the off position short the A and B leads (top right and the one directly to the left of it)

    It will blink a 1..2.....1..2 or 12 three times meaning the system is ready. Then copy down the codes after that. You can google the codes or e-post here for help.

    Other things to look at is the small vacuum line that connects to the heater actuator in front of the fire wall, or the other small diameter hoses for that matter. Mine have started to dry rot near the ends.

    My guess is going to be the EGR valve... but pull the codes first, it helps a lot.

    Good Luck. Mike

    As always, there are many things that could cause this. With a 1995 I would suspect dried up vacuum

    lines which are allowing air to be sucked into the line rather than allow the vaccum to build up. Start

    with simple things and work your way up the line if you are attempting to fix this yourself. Let's face it,

    a rough running engine isn't going to get better once you get rolling. Visually and manually follow all

    of these vacuum lines checking the connections and the entire line ( especially the bottom of the hose ),

    for cracks and leaks. Check your air filter for clogging and intake ducts for any nests or creatures that

    may have made a home while you weren't driving the vehicle. Listen closely for any hissing sounds

    and that could lead you directly to the problem.

    It's a place to start. Good Luck to You.
