Fuel pressure much too high, should be down around 32 or so.
Is throttle valve clean and idle switch working?
Idle should be at 700 rpm, has someone been messing with the base idle adjustment (the black knob)? Base idle is set to 500 rpm then IAC holds it at 700 and (900 when AC is turned on). After a coldstart should be at around 1200 for a short time. Sure that IAC is working?
There are 2 temp sensors, assume you changed the one for the ECU and not the guage. I did not know that either has a gasket.
