Have a random misfire code, this time on #4 and 5. Engine runs normal with check engine light until at road speed you let off the gas to slow down or go down hill. The the engine light starts flashing and then you do get a bad misfire. If you reapply the gas immediately when the flashing starts it stops flashing. If you stop it starts up fine. Replaced the plugs and coil pack. Still same problem.

had the same thing today...pulled a 0300 code and a 0132...new o2 sensor on the way. I never saw a flashing cel before, engine started shuttering at a light, had to keep it revved up. Then all went away.
