Hesatation problem/intake pop sometimes
Okay so I was on my way home from work and I noticed my car was a little hesitating a little bit like a sputter sort of but after 2,200 rpms it's clears out and runs run and the popping happens every so often low rpm's timing checked out okay, plugs wires everything is I'n good shape. Could this be a vacuum leak?
