In GVC, I mentioned my car troubles on one Halloween. My engine's cylinders misfired, causing my steering wheel to shift and lock up on and off. I had to get them all replaced. Almost a $1,000 job. I did not receive a warning. Car trouble is a hassle. I believe that I may have an oxygen exhaust issue. I tightened the gas cap. No success. I am happy you made it there, but not that you had to deal with more issues on top of the original one. Good thing you have some familiarity with mechanics. 😉
