I've been having way too many annoying ignition problems...i've replaced 2 coils and my spark plugs twice, checked them for backing out periodically and still i randomly misfire really bad and sometimes not bad at all. sometimes its there sometimes its not, while it idles sometimes i hear crackling going thru it like its misfiring, and sometimes it just misfires really bad then goes back to normal, other times i hear a pop or crackle noise thru my exhaust and the car feels like it slowed down for a second. i'm sick of it, so what is a good aftermarket coil, and what are good plugs? as soon as i get tires for my new rims i'm gonna get these, will fix my problem and maybe get me some power even. oh and if you have any ideas as to what my problem is or how i can fix it let me know...i can give you a lot more details.
