Re: Exhaust sound: Putt putt putt putt puttYes, it is possible. Usually it only last for a few seconds max though, as the computers remap the fuel and air mixture. |

You should run a compression test. I bet you find a low cylinder and likely a blown head gasket if the valves are not burnt from the vacuum leak. |

I thought a blown head gasket resulted in the engine overheating, coolant getting in the cylinders, etc... which isn't happening. God i hope I didn't blow the head gasket. That would be a monumental job to take on so early in my learning process. |

It depends on where it is blown. Sometimes it blows open between two cylinders and leaks only the compression causing misfiring from lowered compression. |

So I just got my OBD2 reader yesterday, here are the codes from my Mazda P0303 - Cylinder 3 misfire Detected (haha I was right!) P0171 - System too lean bank 1 (Can be explained by above code caused by vac leak?) Yet my mechanic said the code was the remote starter misbehaving and my idling was EGR related. Yeeah. I got new OEM fuel injector seals today, but my wife just drove the Mazda (Crazy insane!) and now I gotta wait a couple of hours for it to cool down  After that I change the seals and put in a new fuel filter. We'll see the result (If I can further chastise my mechanic). |

Based on the video, it kinda sounds like an intake valve sticking or burnt. When it's idling and the pipe is still cold, hold your palm against the pipe, let the exhaust flow out but try to feel if the exhaust sucks in when the misfire occurs.
I know, that's an old trick, but it can help define a symptom. |

The CEL went away on its own. The engine stopped shaking The putt putt went away It stays at 900rpm when idling/stopping It was all the vacuum leak  Maybe tonight or this weekend I will FINALLY do a seafoam treatment, just because it can use the clean up, but now it's all good I haven't seen that car so healthy in years! |
