I've got an 88 mustang and one day it cut out on me. When I got it restarted it ran like crap dumping fuel and it didn't have a strong spark. I've replaced almost everything including the computer, tif module, the plugs, wires, distributor. All fuel injectors fire and all spark plugs fire but it keeps popping through the intake and I can't find the problem. Some of the guys I've talked to said it could be a wiped cam, burnt valves or at the worst jumped timing.

 

sounds like the guys you talked to told you about right. but some of the other guys may have some other suggestions. youre distributer may be about to break too. does it make any kind of grinding noises under the hood?
