Hello again all and thanks ahead of time
My 91 galant is having a weird issue first let me explain what has been so far ... Had a bad exaust leak the mani. Fixed now next replaced the pvc valve and hose .and I also replaced the plugs with ngk iridiums gaped at .44 per the store I bought them at ..... When car is first driven it runs ok but around 3000rpm I can hear like a valve or rocker or something and it seems to go away the car also starts to act like the car is flooded like its real heavy but the boost keeps raising to 10psi . After driving around not realy boosting I can hear the valves or something even worse and I think I hear spark knock at low idle and to try and floor it the car will jerk real hard like out of gas......gonna complete a boost test this weekend but even /ubbthreads/images/graemlins/banghead.gifa leak should not make me valves or lifters noisy after its been driven a bit.... This makes.no.noise ar idle but if you rev it I can.hear a slight wrapping or something???? Coud this be a bad knock sensor ????
