Engine acts like dying
Today when I was pulling into the garage the engine started running real ruff, acted like it almost died, and the check engine light came on for a minute. The oil gauge needle flicted a few times, which that is nothing unusual as that has been happening for years, but it happened at the same time all the rest was happening. I left it running and got out to get my code reader and plugged it in. I checked it but there were no codes. Any ideas?
