I have a 99 ford windstar 140,000kms an wen i start it sometimes it misfires. I changed the spark plugs the spark plug wiring harness and the battery. I took it to the dealership an they told me my battery was too weak so i changed that for a new one(which is 650 cca) so i was wondering wat the problem could be.
