I would like to know cause my car has been running bad for three weeks now and I did what a lot of ppl told me to and it hasn't gone away...... please let me know how it would act because someone told me it might be it.....
if you're leaking air, you'll hear a loud hissing noise. you wont really notice mich difference in idle, it'll seem the same. but you'll hear the hissing noise. eventually you might get a code saying you're running lean.
it happened to me when i didnt rtv correctly with the pi intake install.
