well i have post this on another part of this board but i hope its ok to repost it here as i was not sure where to start but you guys seem to be upset with gm and can maybe give me some i have a 2012 silverado just hit 5000 miles idles very rough 5.3 had to dealer 3 times they say nothing wrong dont bring it in unless check engine light comes on. any ideas ? i checked out 4 others they all have little shake but not like mine their read out says ecm controls idle and is not ajustable .so why not replace it g m cust .assist
said they would replace it but i had to pay for part [forget that ] still dont know if that will fix it there are guys who can set idle up with laptop but will void warrenty just bugs me setting at a light and it shaking like that i had a 2007 5.3 smooth idle but not the 2012 anyone else with this problem ?thanks ??????
dealer said put cheapest gas in it i did not like that idea i keep it at least above 1/2 tank always so i let it go till the gas the light came
on then put in about 1/2 tank of 87 octane real gas in it i try to always get gas at the same place real gas only it seems to do a little better but not like it should be dealer tech told me it takes 30 miles for the computer to reajust to any changes ?? have been using real gas but like i said it could be a lot better thanks
i am about fed up with it cant get anyone to do anything gm wants everyone to be happy with their vehicle huh. well where is that department at i cant seem to find it. thanks in advance for any input
