mcgiiver Posted April 27, 2021 Share Posted April 27, 2021 Wife came home with car running and said all the dash warning lights are on, all of them. Shut car off restarted, same problem and car would not idle, but would run smooth with some throttle applied. All fluids ok. Disconnected battery and reconnected then things were Ok, Scan gauge show no codes at all. Any idea what happened. Seems OK again now. Link to comment Share on other sites More sharing options...
Alexmed2002 Posted April 27, 2021 Share Posted April 27, 2021 Have you recently had the battery tested? Sometimes a battery that's going bad can cause the car to have weird things happen. Link to comment Share on other sites More sharing options...
dgoodhue Posted April 27, 2021 Share Posted April 27, 2021 All the warning light on mean nothing other than it has check engine code, they do that to get your attention. You should have scanned the codes before you disconnecting the battery. You will need wait for the code(s) to reappear. Link to comment Share on other sites More sharing options...
