i just installed new 27Lb fuel injectors and took off my stock ones, on my 1991 camaro z28 5.7 and the idle in park is at 2500 RPMs then falls to just under 2000RPMs. but when in drive its around 1000rpms (normal)

why do you guys think im idleing high and how do i adjust it?
-thanks

 

They made camaros in '91? Just kidding. Sounds like it might have something to do with the injectors. Just kidding again.

Is it possible you lost or damaged one of the o-rings from the bottom of the injectors, where they plug into the manifold?

What mods do you have that required the larger injectors?

Who tuned it for the larger injectors?

 

the mods are-
true ram air
bbk underdrive pullies
strate piped exhaust
58mm throttle boddie
intake is ported and pollished
MSD ignition cap, rotor,coil,wires and pluges
Adjustable fuel pressure regulator
Jet stage 2 performance chip

i highly dought that i damaged the o rings bc i took my time and very cautiouly installed them. there no leak or any thing i can see wrong,

i looked at the rpms closely and when it starts it revs to 2500 then drops to around 1500. its to high, before the injectors it was around 1000rpms in park.

no one has tuned it yet bc im waiting to get a new ecu with a programer installed. and when i get that im having it dyno tuned.

 

i looked up the part number off the injectors and it said they are bosch/ford racing 24LB fuel injectors. made for corvette and camaro L98tpi

so i guess they are 24 instaid of 27 witch is what the add said online.
