i have not checked for vacuum leaks but based on the way the car acts, runs perfectly then has it's stalling episodes. leads me to think electrical since the problem is somewhat intermittent.

is there such a thing as an intermittent vacuum leak? i'm not against searching for vacuum leaks. i had ruled that out just because of the way the car acts.

example- after i replaced the maf sensor i had 130 miles of no codes and no problems.

is there a certain place i should look for vac leaks that's problematic on these cars? i've read on the supercharged cars there is a "y" connector that often leaks. is there something similar on the n/a cars like mine?
