whats up i got a 1989 crx with a LST,obd 0 and on fmu all stock except for the fuel pump.Car runs like a champ then all o fa sudden i stop hearing my bov and boost does not feel as strong.the both vacuums for the gauge and the bov are on one vacuum t.Do you think that would make such big hit in performance?....also every now and then the motor sputters a little in the freeway

check for cuts in the vacume lines and check your iacv wire conections.

thanks.checked all the vacuums they are good.i just took it down the street and it feels weak can barley break second free.im running a missing link,do you think a dirty missing link filter could cause it?
