I would say its just your a/c compressor kicking on and off.As long as your ac is cold everything should be normal.Yeah I feel mine too but my idle is a little to low I have to try and get it adjusted I have fly by wire,I think it has to be adjusted by a pcm.The tahoe has a cable,and is easily adjusted.Im not sure what the idle is supposed to be but with a slightly higher idle you might not feel that vibration as much.

I agree with Whipple1, it is probably just the compressor kicking on and off, the same thing happens with mine, and I had the dealer look at it, and they couldn't find a problem. :Chevy:

So do I, except for one minor detail; Tahoes come with either the ETC (Electronic Throttle Control) or the throttle cable, depending upon trim.:)

I have two friends one with a 2002 tahoe and one with a 02 suburban and they both have cable,I guess I was assuming they all had cable.My truck is an 02 and has the (ETC) I guess they changed it in the newer years.

I don't know exactly how GM packaged in the ETC with the different trim levels. My 01 has the ETC. My brother's girlfriend's 01 has the ETC. Both are LT models, so maybe it was only used in the LT trim. I'd like to know, so I will do some research and let everyone know.
