Can anyone help please..My 1990 mustang GT is my daily driver car and it has been running fine for a while, but the other day while driving the RPMs just started dropping and the car just shut off. I tried restarting and it would just turn over and not start. Thankfully I wasnt far from home and a buddy towed me home. The next day it started up fine. What the heck!! But, later that day the same problem happened. What is going on? is this a known issue for this year mustang? it is driving me crazy.
