changed plugs still seems to run rough, also the ac isn't working now ???

 

Okay----how can we help then?

Might want to post if you can or have read any MIL codes---those are helpful and without them you'll get a long list of possibilities. MIL codes help narrow the problem down.

When did the A/C stop working? How was it performing before it stopped? Has it ever been serviced or at least checked over by an experienced and knowledgeable A/C service mechanic?

Gotta post better questions in order for those of us willing to help to get the ball rolling for you!
