After doing some hard driving, i came home and parked the car for about 5hrs, then tried to go out for dinner only to find out that the car was would not crank. After sometime i got it to crank and when it did, it was running on 2cyl, and could hear knocking on #4. Check the spark plugs, and #1 & 4 are not getting Spark. ( My Eclipse did this and was the CAS) Could it be the same problem again?? No CEL light, only the ANTI LOCK light, and it wasnt there before this.
