Service engine soon light
MY light came on the other day, then my engine started bogging down, and jerking. I was on the highway about a few miles away from home. I looked at all my gauges and they looked OK, so I slowed down to about 55 and just limped home. Half way home the light started flashing, then went back to being steady. Once I got home I opened the hood and everything seemed to look ok. I took it to autozone later that night and got the code P0300, but I know there could many reason for this. I also noticed on the way back from AZ, that y oil guage is now steady on 120, and does move when I start my car, any idea'*?
