Car wouldn't idle
This morning my car started really rough and would not idle. I could get the car started by giving it some gas and it would stay running if I gave it gas. I have a digital voltage gauge. When I let the RPMs get below 900 RPMs the voltage gauge would drop down to 12.0 volts. At 1000 RPMs the voltage was 14.6v. I let the car warm up and it still did the same thing. If I took my foot off of the gas the car would stall. It would start hard and only stay running with gas applied. At low RPMs the voltage gauge would drop to 12 v and stay there. Just when I was giving up on work today and using two feet to drive the car into the garage, I got out to move a trash barrel and the car stayed idling. It ran fine and the volt gauge was at 14.6 v at idle. I drove 25 miles to work and tried restarting and it ran fine. I had a check engine light on before this happened and have not read codes yet. The check engine light had come and gone a few times in the last two months. The low voltage reading is strange, as if it wasn't getting a turn on signal from the computer oir something.
