I found that a lot of times it is a bad plug wire, or one that is arcing off the block or body. Do you get check engine light?

I know that this will sound Stupid. Change the Fuel Cap. If the Seal on the Gas Cap is Bad it will allow Air to get into the Fuel tank and cause your Rough Idle.

SOURCE: Needing to know why my Yukon's gauges stopped working.

You need to replace cluster, 99-02 Silverado GMC all will work even if it has a trans temp truck is pre wired for it. I put a 02 Denali cluster in my 01 silverado no problems. GM can reprogram hours and odometer if you want.

SOURCE: spark plug wires are arcing

If the wires are arcing that means that they need to be changed they have worn out and they can no longer keep the high voltage inside the wire just replace them about $100 and all your problems will be solved

SOURCE: when putting truck in reverse

double check u-joints before suspecting internal problem with transfeer case. Coupling between transmission and transfeer case could be worn, as well as rear slip joint on tail shaft. If not rebuilding the transfeer case yourself, get plenty of refferences before hiring some one to overhall transfercase. InMrFixIt

Have the batter load tested as there may be a faulty bridge inside the battery. Never jump start from any point other that the battery post positive with the negative cable attached to the engine If you continue to jump the way you described then sooner or later you will cause a power surge which will fry the CPU.. Check all cables are shiny clean and tight all the way from the battery posts to the starter.

Brake lights/rear turn signals


I had the same problem with my 1999 Yukon. The electric board needed to be replaced. Rust starts to build up and shorts out or blows the bulb. The dealership charged $73.60 for the part and I installed it myself (Saved $30).
