My 93 K-1500 350 w/ 230,000 miles idles smooth but requires a lot of gas pedal to to start increasig revs, then comes on sharply. The engine has a mild lope that's more noticeable at low revs. It's particularly annoying while stuck in slow traffic or in parking lots, or other stop/start situations. Sometimes engine will stall after starting, but will start right back up. Does anyone know anything about this, or has anyone had this issue? Thanks for any help anyone can provide.
