    idle dipping while stopped

    I have a 1988 k2500 that starts immediately and idles very well. However once the truck gets to operating temperature the idle will dip for a split second when I'm stopped at red light. I have also noticed the dips get worse the longer I idle while in drive. The truck has never stalled when this...

    K1500 AWD SWAP

    I've got a 97 GMC K1500 short bed. Wondering if anyone has heard of or done an AWD swap?

Thoughts and ideas for making this happen is accepted

    Fix - Wipers won't "Park" at bottom of windshield.
