automatic cruise control, unwanted
00 6.0 4x5sp posted a topic in 2000-2014 Silverado & Sierra HD2000 6.0L, 5 spd, 4x4, ex-cab, swb. Notice: 5 speed, manual. Get this truck over (about) 1700 rpm's & it'll maintain speed (foot off the gas) till it hits a big enough hill. It'll gain speed/acceleration down the hills. It's kinda like the cruise control is on. The big problem is when out of gear & rolling, motor will rev way up, eventually bump itself down, then wind-up again. BIG PROBLEM- Can't just take it out of gear & coast down, unless you wanna hear that motor wind out. Usually a buzz sound, similar to a street light buzzing happens around the same time, not sure if related. Already replaced a throttle control. Have been told wiring problems are common for 2000? Any ideas ? Thanks.
