This is the '94 RMS
Idle 35-36 PSI
Hit the throttle (quick snap) in park jumps to 45
Let off throttle drops down to 33 then back to 36
Hold throttle down in park 33-34 PSI then rises to 36 PSI once let off
Idle with no FPR vacuum 46 PSI
Unplugged FBR throttle snap 46 PSI
Plug FPR back in PSI drops to 36 again
KOEO PSI jumps to and stays at 44 PSI
I know the fuel filter is ooooooold and needs to be replaced, but can't say it'd clog to cause this issue.
Can't take a drive and watch gauge. Hose isn't long enough. Trying to borrow one...
Thoughts?
