Hard to start/high initial rpms

[Nixon1]

I've had a sh*tload of work done on the car...things like the IAC valve, coolant temp, and throttle position sensors were replaced...and it's got BRAND NEW 19 lb/hr fuel injectors. It's running a very steady 13 degrees of timing on 93 octane gas. It's got decent wires, new plugs, a new cap and rotor, and a new Blaster TFI coil.

This problem has been here all along, since before and after the repairs, and I've had people tell me this isn't normal behavior. The car is a little hard to start all the time, even after it's been thoroughly warmed up. It'll crank and crank or a good 2 seconds each time. Sometimes I can let my finger off the key before it actually 'starts' and it'll start itself. That's the first problem.

Second is, when it starts, the rpms fly up to around 2000, and slowly fall down to around 1000, until I tap the gas or let it warm thoroughly or give it another minute or so, in which case it falls to a normal idle of around 700-750.

It throws no check engine lights, and runs great besides this! What could be going on...it seems to me like it's getting extra fuel. Could the fuel pressure regulator be the cause? I want to check my fuel pressure with a gauge via the Schrader valve, but none of my friends have one and they cost like $45....I'm broke.

Thanks guys!
