What to do if your GMC Sierra Voltage Gauge does not work?
GM has had a issue with the clusters in the 2003-2005 trucks. The cluster will be replaced for free for your truck if it has less then 70k miles. I would take it to your local dealer and tell them that the voltage gauge sticks at times. They should order one for you, takes 1-2 days and replace it for you at no charge.

When do the engine RPMs bounce when driving?
It seems to happen primarily when traveling between 45-55mph. When driving, slightly accerating, the truck is doing about 1100 rpm in its 6th gear. The engines RPMs seem to bounce back and forth 50-100 rpm. It is not the usual ‘bounce’ you get from v4 to v8 mode, it is happening while accelerating which i can see is keeping it in v8 mode.
Why does my Silverado go faster in V8 mode?
It is not the usual ‘bounce’ you get from v4 to v8 mode, it is happening while accelerating which i can see is keeping it in v8 mode. To add to it, it is no happeing in really any other gear or driving condition. Go faster with more rpm, problem gone. Its seems to only show when “lugging’ in the low rpm when locked into the high 6th gear.
