Customer Question

The truck is stuttering. Replaced MAF (or MAP?) and IAC sensors. Seemed to do the trick yesterday then today almost as bad as it was before I replaced sensors. Am thinking air leaking as I hear it escaping from somewhere? Also, one of the vacume hoses either is clogged or has no function but?
