New owner 08 Malibu weird issues
Hello everyone! I'm a new owner of a used 2008 Malibu LS 2.4. I am needing some help. I've owned the vehicle for some days now and yesterday I had an issue. Here it goes...
Yesterday night, I came back from a bumpy trip in Baja California. I crossed the border, turned my Malibu off at the gas station and then had no start. Lights, radio, etc. All worked. Decided to wiggle battery cables (as this was my first suspicion). Miraculously, it turned on thereafter. However, I got a check engine light and erratic shifts.
Today, I took it to get scanned and everything was back to normal on startup. No check engine light. I still retrieved the codes and here they are: P0455 (evap large leak)- note I passed CA emissions a few days ago. P0700 (TCM related code so pulled TCM codes) TCM codes were: P2544 and U0073. I did a little research and I'm inclined to think this is a TCM related "glitch." Not sure what to make of the codes now since they are gone. I did clean and re-tightened my battery cables (not really dirty and I tightened positive terminal a 1/2 turn with my wrench). I also took a two hour trip today with no issues coming up. Any input would be great. I have 140k on the clock.
I'm happy to be part of the community and look forward to getting some dialogue started. Thanks!
