Why is my PT Cruise engine missing when it is idling?

Answer by  Joe1010us (239)

Its more than likely the vacuum system. Check and listen for cracks and leaks. Check your cars computer for codes by using the key trick (look it up)

sounds like it might be as simple as a tune up, remove one spark plug wire at a time till you dont hear a change, replace that spark plug and wire

Most likely cause of missing is a bad spark plug or bad spark plug cable. A mechanic can diagnose which cylinder is causing the problem with a diagnostics computer.
