lately while im driving the check engine light will come on, be solid for about 5 minutes, then it will flash for another 5 or 10 mins then it will go off and stay off.... as well sometimes the red lighting bolt in the bottom right hand corner of the dash will come on and flash and the truck sounds like its running on half the cylinders... anyone know what would be causing these things to happen??? thanks
generally, the flashing cel means your cat is in trouble (not saying this is happening in your case). The lightning bolt usually means an electronic throttle control problem. Head to an autozone or advance autoparts and they can pull the code for you for free. Even if the light isn't on when you get there, it should still be stored in the pcm.
well if when u say CAT you mean the converter then it isnt that, cause i dont have one haha. I have a super chips programmer, i think it has a code reader built into it, i never thought of that. I dont see how the lighting bolt could be the tranny.... cause it drives fine it seems more like an ignition or fuel problem to me when that light is on.
