Correct psi?
I have installed my replacement injectors, I just want to make sure my pressure testing is being done correctly, and also that my pressure is correct
With gauge connected, and key turned on, pressure jumps up to 45-48 psi
turn key off, and pressure does not drop right away, after 30 min I still had 28 psi, is this good? no lines were pinched, not sure if need to if doing a injector leak down test?

Re: Correct psi?
That all sounds reasonable, basically within test equipment and parts tolerances.
How does the car run?
"If it RUNS good, it IS good".

Re: Correct psi?
Thank you for the fast reply, really appreciate it
I would have like to start it up last night but noticed I had a cracked spark plug wire, just replaced last fall dangit, just my luck.
Tonight on way home I will be getting a new set, and will post back if/how it runs, fingers crossed, hope all goes well

Re: Correct psi?
Good news, car starts and runs, weird thing is it didnt idle correctly till I unhooked a vacuum line, just connected EGR that was missing.
are my vacuum lines right? the sticker under my hood shows that egr connects to solenoid, other side of solenoid goes to a t, one goes to throttle body other goes to top of a vavle thingy that goes to charcoal canister, this valve thingy has 2 connections, the bottom one goes to the plenum....is this correct?
I have seen so many darn diff vacuum diagrams i dont know what is right
also, my firewall has 2 small plastic lines, one goes to heater controls correct? does the other go to crusie? should these 2 lines connect to a t and then to plenum back by the FPR?
thanks in advance again!
