2009 Honda Fit limp mode at 60 mph?
Having problem when getting to 60 mph. Car goes into limp mode and if I scan it will show p0301, p0302, p0303, and p0304. If I turn off key and check again misfire codes disappear. Car runs perfectly smooth at startup and driving normal Can turn car off and back on after going into limp mode and it runs smooth again. I've had the car for 1-1/2 years previous owner passed away but always serviced at dealership. Car has 157,700 miles on it. My daughter doesn't drive much so probably only put approx less tha 10,000 miles since getting car. Fit is getting 29 mpg with all city driving and AC running. South Florida. Could it be bad gas? or something besides coil and plugs? Just started this behavior within the last week.
