So I had my buddy pug in his OBD2 computer into my S2K and sure enough 7 different codes came up. Six of them being that my engine is misfiring on all cylinders and then random engine misfire. Also it says my V-tech solonoid is going bad. I need to know if this is all something I can fix myself in my driveway. I'm going to change the sparkplugs and wires also buy a new solonoid. Need HELP please!!!! Thanks all.
