I have a bronco with a 5.0 EFI that was running fine. I wqs doing a brake job on it and when I started it up, it ran very rough and blew black smoke and smelled of raw gas and made my eyes burn. I was able to get a code scan after a few attempts and got codes for the coolant temp sensor out of range, air charge temp sensor out of range, MAP sensor out of range, all of which have been changed, and the o2 sensor not changing from rich, I'm assuming because of the raw gas in the cylinders. I also changed the fuel pressure regulator thinking that may be the cause, but it didn't fix the problem. I don't know what else to change unless I change all the other sensors and then I still will probably will have the same problem. Help!
