My 2007 Nissan Altima went from running fine to shaking bad and running rough when my daughter was driving. She said the service engine soon light was coming on and off. When she pushed the gas.
When my husband turned it back on it shook and idled very rough. Could using 100%
gas, for a change cause this?
the octane change won't cause this- the light says to check your engine- so- it is time to service your engine- hopefully, a routine service will fix it-
Sounds like a O2 sensor
