Default Random Miss... something bad happened

About a month and a half ago i installed long tube headers and true dual exhaust... about 2 weeks after i burn a wire and get a blinking ses light... get it fixed and went on driving.... Recently i got the same missfire conditions and figured it is prolly a burned wire...
i checked them all and there was nothing... thought it was cause one plug was loose, but thats not the problem either... ive run out of ideas... im about to get underneath the car to investigate some damage done by a rock that hit something under my car... this was a couple hours before my car started crapping out on me... the opti is not old... replaced less than a year ago....
My low coolant light is on, so i fill it up and find out that i was not low at all... so im not sure what the deal is with my car... I have connections at a dealership so my extended warranty may not be a problem even with my mods... any ideas would be greatly appreciated... may i can get lucky and find that the rock or something broke something vital and i need a new engine... perhaps use the opportunity to swap something sick or build something sick into it...

Replace the plugs and wires anyways. You could have fouled one or a plug wire could be arcing. The low coolant light stays on in alot of LT1 cars, most people just pull the sensor out. Ignore that, its not really a problem.

Sweet, so pulling the sensor will make the light go away?

be happy you found the problem and be sure to use zipties to keep it from happening again.

yes unplugging the low coolant light does make it go off. or you could just spend the 15 dollars and fix it.

Don't ziptie wires together they can arc off eachother. Use Looms to keep them seperated, there are specific looms that pull the wires inwards but don't let them touch. I'll draw it the best I can on the keyboard (LOL) say the plugs are the .'s and the /'s are the wires.... ------ ./ \. is how the wires would look with the type of loom holding it that I am talking about.

thats true only if they run parallel, i didnt think about that and i was meaning ziptie them off to a solid mount or something to pull each individual wire away from a heat source. there should be looming in the other areas where the mass of wires goes through. if not get some looms. moroso makes a setup for center bolt covers. maybe some of those will work.

Just unplug it, dont remove it. Unless you like a 3/4" hole in your radiator.
