I have a 93 Lx that will run fine at idle sometimes, then will start missing on two cylinders, and when I put it in gear it runs really rough and stalls out. New to mustangs so I have no idea whats wrong, any help would be appreciated

CEL on? Check codes

Sally91

nope, thats whats wierd about it!

Babybudistmonk

I would still warm it up and have it code checked. You may have some CM codes in there that wont trigger the CEL.

Almost sounds like a coil pack going bad. Have you tried switching your coils to see if that makes any difference? What do your spark plugs look like?

Sally91

Everything is new, ive talked to some people and they say its the dis module has gone bad, that its very common in the 4 cyls

Babybudistmonk

It could very well be the DIS. However, that is kind of costly to replace. I was trying to eliminate some possibilities here that you hadn't mentioned working on. If the rest of your ignition system is known to be good, then go for it.

yeah im going to the junkyard tomm to see if i can find one there as a temporary fix

Sally91

No junkyard has the part any other ideas?

Test the one you have, make sure it is bad. Then buy a new one
