Tail pipe is making popping while idling, just replace head gasket couple days ago to fix blown head head gasket

  1. the popping noise is a indication of a cylinder firing when an exhaust valve is open. This could be caused by bad ignition timing or valve timing. Meaning either the timing belt isn’t lined up right(most likely) or the distributor timing is off.

    When you put the timing belt on, you need to rotate the engine a couple of times and then recheck before reassembly.
