Vacuum leak on that side of the motor. How does it run. Clogged injector maybe?

wouldnt bad fuel press **** it all up?

and where could i look for a vac leak? i dont think it has one...but i could be wrong... but as far as i know, ive looked and dont see one... what should vac at idle be?

and the injector thing is exactly what im thinking, but just looking for more ideas

as for how it runs, like ****... backfires/hesitates/bogs... its bad, but only when it wants to be down at low rpms, and always above 4k

intake gasket maybe?

did you delete the smog crap yet?

dimebag

all the gaskets from the heads up were recently replaced as well, and all set in correctly, i dont think its that at all... thx tho

dimebag

smog **** is all still on it... everything sept the cats, and the pipe going down to the h pipe is fully connected

AdderMk2

the smoog pump has been known to cause backfires... you dont hear it though cuz it gets muffled by the cats... Delete the smog system and I bet your problem goes away

dimebag

see 2 problems w. that tho... its not slight... its bad, real bad, and it didnt always do this, it jst came up w. in the last month, and the cats have been gone since january. also cant remove the smog **** compleetly because i have to pass emissions here.

do you know what it is about the smog system that causes it?
