Tahoe issue??

[macojoe]

Well it started this morning, and went right to high idle, but after a min or so started doing the same thing, but cleared up much faster then before also. So my son is going to do it again this week as it is snowing again now. We will see after the 2nd time if we can get it right//
Ferm I had that problem in my 02 truck and it was that purge thing, I had a friend change it and it was good after that,but the light would stay on all the time in that truck.. I am sure if its not fixed now that would be it, the ck light went off after a little while and has not come back on so far, we will see? Thanks for reminding me!
I am going to get a oil change this week, but when I had the other truck it also had the 4.8 and bot the same gas mpg.

My new question is I have called about getting breaks for the Tahoe and it has 4 wheel disc, they all ask me if it has one or two pistons, I will have to look to find out. But My other truck had 2 pistons, and I was wondering does it matter?? I would think the dual pistons would be better? So if I buy the dual instead of the single will they just fit in place of the single with out problems

Thanks guys!!
