I have a 1990 Mercury cougar with a 3.8 v-6 and all of a sudden I cant keep the car running. It sounds like it's running on only 3 cylinders. When I give it a lot of gas it seems to straighten out, then as it idles down it runs real rough again and stalls out. I cant keep it running. The wires look fine. This car was running fine and all of a sudden this happened out of the blue. Any suggestions on what to look for first?
