Fuel pressure for b20b

[llestekb20]

What's the stock fuel pressure for a stock b20b.i was told to take the vacuum hose off and then adjust it to oem specs


Any help or info would be awesome thanks

i have mine set to about 42-44 psi and it runs pretty good. i set mine witth the vacuum hose in tact though
when you disconnect the vac hose it revs up a little so idk why you would set it like that.

what ecu are you running?

I'm running obd1 p75 but for some reason it's running rich

are you running a stock fuel pressure regulator? if so try and pick up an aftermarket adjustable fpr or grab on of those B&M ones. they are a little cheaper because they essentially turn your stock one into an adjustable one

Mine is b&m

gotcha. no CELs? have you checked your o2 sensor?

Cel randomly and it is for my "heated oxygen sensor" but it comes and goes and my idle slowly bounces around so I have to keep cleaning my iacv and when I do the cel turns off til it gets dirty again so I think I need a new iacv as well

replace your oxygen sensor! the o2 sensors have a heater on them because the exhaust gas needs to be a certain temperature in order to get a good reading. if that heater is not functioning properly it is feeding back an improper signal to the ecu. change it out and you should see an improvement in afr. may even improve your idle
