I have a miss in the motor, have tried a tune-up, also had catalytic converter checked, put in new fuel injectors, and it is still missing. If you run for a while you have to rev it up to high rpm's, and so far it will go after revving. It is getting worse with time. Started out just doing it after you had driven it for a while and stopped, and then when you would try to go again, it would happen. Now even in the morning before having driven it, it has done it. Mostly after being driven a while. Please help. Any suggestions would be greatly appreciated.

Can be caused by a weak valve spring.
