Check engine light keep blinking
My check engine light keeps blinking when I get
between 40 and 50 mph and shakes between that
speed. When I take it to AutoZone and they scan it
the code is p0204 and P0304 I've changed the
spark plug the coil pack they say the wire harness
is working they say I need to change my fuel
injectors. It says 4th cylinder misfire what do I do,
what is it, what could it be.
If plugs and wires are good,it may be the fuel injector,but could all so be a bad valve on that cylinder all so.
Swap the #4 fuel injector with another injector to see if the trouble code moves to another cylinder with the injector. If the code moves with the injector then it is bad. An injector wiring issue could also be the problem.
If the miss moves from cylinder to cylinder randomly you may have a bad fuel pump.
