Yeah, I was just wondering what normal was for the new Ecotec. The old engine 5.3L Vortec, evidently idled the same I just didnt pay any attention, and at the end I was wondering if there was a difference in say an 07 Silverado with the 5.3 and an 07 Avalanche or Suburban with the 5.3. As far as I know the 2014 Silverado/Sierra was the first application of the Ecotecs.

Really... I could definitely be wrong because in the previous vehicles I didn't pay to much attention. It was a well known engine. I was just curious about the new ecotec. Could there be a difference between the Silverado and the more SUV like Avalanches with the same engine.

Cool thanks. Appreciate the info. This is my first Silverado and I started with the 2014. Before that I had a 2011 Suburban LT Z71, 2009 Avalanche LT Z71, 2004 Avalanche LT Z71. All three had the previous 5.3L Vortec and im pretty sure it idled a little higher. Thanks again and glad to be a member looking forward learning more on here.

Hi, new here. I searched and could not find an exact answer so I thought I would ask. What is the "normal" idle rpm for the 5.3L ecotec? Mine seems to idle right at 500rpm. I am not having any problems it just seems low. Thanks in advance 2014 Silverado LT Z71 5.3L
