As of late driving on the highway my evo has been throwing a P0300 ce code. When I looked it up it came up as a random misfire code. Now I started with swapping plugs (twice), no luck, so I then went and ordered some Magnecores, and still no luck. It only seems to throw this code when I'm on the highway and staying steady at around 80, car suddenly loses some power, light comes on, then car goes back to normal. Any suggestions? Thanks!!

Is your car stock ? If yes take it to the dealer for a TSB for code P0300 (misfire) they should be able to take care of it. Oh and FYI Magnacores suck @ss , sell them to someone else you'll only be happier without them. Go look on Dynoflashes forumn under vendors forum... he has alot to say about magnacore, or do a search... you'll see.
