Check engine light flashed now on

Go get ur cel code read. Autozone will do it for free. More info easier to help.

The flashing check engine light and the symptom you described indicate you have an engine misfire. The most common problem is the coils. You have two options. You can either scan the engine computer for trouble codes that will help you identify or narrow down the possibilities. I'm going to bet that there is one or more of the following codes. P0301, P0302, P0303, and/or P0304. The other option is to get a spark tester and test each coil one at a time to see which one is not working.

At 150000 miles the plugs start to fail under hard acceleration the higher compression blows out the spark before it ignites the fuel. Random cylinder misfire causes the check engine light to come on. change the plugs!

Hello I have a 2007 Magnum 2.7L that has code p0302 cylinder#2 misfire seems to have coolant loss but can find no leaks. Recently had another code p0300, so both are active check engine light started flashing but stop and stayed solid. Not driving it. Replaced spark plugs should I replace coils? Any feedback please.

It likely had water on the ignition system. The check engine light will flash for misfire. The VSC light is on just because the check engine light is on. You likely have it dried out now and its fine. You just need to clear the codes. Autozone will do this for free.

my durango does that too, its either the multi function switch (turn signal arm) or light switch, i haven't fixed it either

any time the check engine light is flashing it is the on-board computer telling you that the engine is misfiring, i think i would take it back to whom done the tune-up sounds like they may have cracked a spark plug or damaged a plug wire when they tuned it up.

the flashing represents misfire codes i would try a set of autolite plugs and go from there of course you will have to go somewhere to get the light turned off possibly auto zone

Can be many things, need to hook it up to scanner.. if u live close to AutoZone or Advance Auto they will check for code free.
