Yeah Ive tried the mixture screw abunch of times and it does nothing, its drivable but when I take my foot of the gas itll rev to 2600 and then die out or just die out. It really sounds like a vacuum problem but I checked every vacuum line and connection a dozen times
did you physically check or replace each vacuum line? they are really cheap to do all of them, and over time develop pinholes in them, you cant see these, but enough of them will cause problems
