#4 cyl missing
 

hello , i have a 2001 sebring conv. 2.7 liter , # 4 cylinder not firing , it has a coil for each cyl. i tried swapping coils around no help , i have 13 or so volts going to the green wire on the coil but nothing on the brown wire , i think its supposed to be a pulsing ground?,i tried the other two cylinder coils up front and the brown wire pulses on ohms, nothing on # 4 , does this mean i have a bad ECM?, ive found remanufactured ones on ebay for 199.00 i dont mind spending the money , but just wanna make sure thats what it is , im just not very famalier with this type of ignition system , any advice would be appreciated , and by the way the car has 93,000 miles thanks

brown wire is a ground pulse yes do u have that?

ground
 

no i have no pulsing ground on the brown wire on # 4 cylinder and thanks for the help , would this be the pcm or the ecm? this is bugging the crap outta me,,,, were pretty close we live close to bham alabama

Check the wiring carefully before you replace the PCM.

thanks ill definitly do that because the problem started a couple weeks ago ,intermitently and now it misses on that #4 cyl all the time

yes chk wires b4 pcm replace 9 times out of 10 the pcm is not the prob.
