My car has a rough idle, I mean it almost dies and the check engine light comes on. I did a code check and it passed. I unhooked the MAF sensor and the idle improves but is still rough. I did this several times unhooking the sensor. How do I check the MAF senor anyway? I've checked for vac leaks and came up with nothing. thanks
 
Plugs and wires? also i had a DIS go bad no codes! samesymptom idled like crap and ran crappy.
 
Plugs and wires are new. One other thing, it ran fine and all at once started driving like crap. Is there anyway of testing the dis? thanks
