On my way to work, at 70 mph, the check engine light came on and the SUV was running noticeably rough. Took it to local Oreillys Auto Parts and they plugged in. She's throwing a P1135 code with cylinder 4 misfire. Check engine light flashes in random quantities under acceleration. How does an 02 sensor cause a particular cylinder to misfire?
