Problems at Start-Up

[Outlaw88]

I have an '88 Bronco with a fuel injected 302. A few months back when I went to start up my bronco which I never had a problem with before, it died after about 5 seconds. When I turn it over the rpm gauge hits about 1,700 and holds for around 10 seconds and than just drops and it dies. The only way to keep it running at start up is to hold in the gas pedal which seems weird to be seeing as its EFI. I have since relapced the alternator, starter, battery terminals, as well as having the battery checked. Just yesterday I did an engine flush and replaced the fuel filter. But this morning at start-up it died on me again. I am running out of ideas but i've heard a few mentions before like replace the pcv valve, or it could be a sensor, only I know nothing about sensors or where to even find them. Can someone please give me some information that I can put to use and hopefully fix this problem. It is quite aggravating, I love the EFI for the fact that you can just turn the key and walk away while it warms up, or use the remote keyless entry to start it up. Which is something I would like to add to this, but first I need to solve the problem as to why it dies like that. Could it have anything to do with my exhaust manifold being cracked and perhaps not getting enough pressure? I've even removed the gas cap on start up thinking it was vapor lock, but nothing seems to help. Any suggestions would be greatly appreciated.

I was having the same problem with my 1990, at first I just turned up the idle on the throttle body, on mine it ended up being the pcv valve was plugged up. It only cost $3 for a new one.
