Question about 1999 GMC Yukon
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.

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
