2007 1SG STS v8 awd
I recently changed my o2 sensor. Engine light is off but I still have hesitation and a misfire under heavy acceleration or under load. I. Thought the o2 sensor was causing this. If I accelerate hard the engine light would flash along with the tc light coming on. It would then both go off. What could possibly be causing a misfire under load/acceleration? And not throwing any codes setting off the engine light. If the light would come on I would have somewhere to start.
