I am having an issue with my LTZ. When it is sitting idling it almost feels like a misfire, an engine stutter, or bad gas. When driving down the road I can feel it a little bit. Refilled gas tank and it still has same issue. Wife states that she feels as if it is sluggish while trying to accelerate. I noticed this a little but nothing to major. At first I thought that it might be an engine mount but when I place it into drive and press brake and gas it only slightly moves. It is not throwing any engine codes, but it does have "Service Suspension System" however that is due to most likely the module being bad because I replaced the compressor and it worked for around 20 minutes after installing. The next day it wouldn't work and I jumpered two wires at the relay and it was working. So I guess the question is:
1. Are the two related or could they be related?
2. Is there anything else that I can look at to determine issues with the idling?
I able to use most tools in the garage, since I was an electrician in the Air Force.
Thanks ahead of time.
have the same problem?
