my cx is having a similar problem... ive changed my plugs, wires, rotor, cap, fuel filter, o2 sensor, and my exhaust still smells like crap half the time, and i get cel #1 (bad o2 reading) all the time (its weird b/c it resets every time i shut off the ignition). now im thinking my ECu is bad... i cant figure out whats wrong
i got a weird one hte other day, it was some sort of cylinder misfire calculater -- basically meaning the sensor was malfunctioning.
now, to add to the discussion I should make the note that I am getting around 24mpg right now, which is far below average, and thats the SAME whether im driving hard or driving easy.
the smell is sometimes there at idle, but usually its after a hard drive. there is a serious carbon deposti on the inside of my stock tailpipe as well
