Vacuum readings during idle...
I have a b18bb1 swap in my car. During WOT or 3/4 throttle it bogs horribly and decelerates. I have to give it light throttle for it to not bog. I've replaced everything I can think of to cause bogging. Replaced: air filter, fuel filter, O2 sensor, plugs, plug wires, all internal dizzy parts. I can't figure out what's causing this. My next theory that's causing my problem was a clogged cat. I hooked up a vac reader. During idle I'm getting a solid 18hg rev it up to 2500 and it shoots to 20-22hg then under decel it shoots to 20+hg like it's suppose to. If I'm not mistaken I should be reading 0 to -1hg past idle right. So could a clogged cat be my problem!?
Cliffs:
WOT or 3/4 throttle bogs and decels on own
Replaced all that's higlighted
Idle vac reading I see 18hg
Rev to 2500 I see 20-22hg
Possible clogged cat?

Re: Vacuum readings during idle...
Idk about vacuum readings but I'm having the same problem. The car runs fine when its still cold? For me this only happens when its fully warmed up. I've narrowed it down to me burning oil. I just think because I burn oil during vtec, it gets in my chamber and lowers octane rating, thus causing a loss of power.
I'm guessing your car burns oil during higher rpms?

Pretty much hot or cold I can't go past 4k or it would bog and let the rpms drop. If I give it light throttle it'll go but I can hear it misfire. Possibly a ignitor?
