My 2010 Jeep Commander has been running rough lately. Knew I needed to take it in, but didn't. This morning, check engine light came on. Not the flashing one of death, just solid. Pulled over, did key on/off thing, DTC error P0301 comes up. Just googled it, engine misfire/timing code. Called dealership, guy on other end is clueless, can't get me in until Thursday. It it dangrous to drive it around? I'm thinking not, how bad could an engine misfire be, right? I'm thinking all that will happen is shitty mileage and shitty power. But, then again, I registered in 2013.

Gets really exciting when the misfire occurs late in the exhaust stroke instead of the compression stroke.

Egads man!
I never let my plugs go more than a couple years, maybe 3 at most. Used to do them every year when I was only driving 1 vehicle. Plugs or coils, if it was a crank or cam sensor, it'd be pretty non-functional. |

Is it back-firing? IE; loud BANG! occasionally, or just sputtering and spitting? I'm not sure if that's a thing anymore or not, but detonation with either valve open, ( intake or exhaust ) can cause other issues. |

It's like it doesn't get enough gas from 0 to around 1500-2000 RPMs. Over 2000 RPM, it runs fine. |

Engine misfires are fine until you have to replace the cat or the car burns down because the cat got too hot and burnt up.
Seriously, get it looked at and quit driving it, before you break something even more expensive. And next time, don't buy a Chrysler product. |

no, don't drive it get it fixed, the catalytic converter is going to load up with unburned fuel and become damaged, your bad coil or spark plug could get a LOT more expensive.

Theres an explosion occurring inside your engine at the wrong time. What could go wrong ?

Mr sparky igniting mr fuel air mixture at the wrong time makes Senor engine very sad. Seriously ignition timing is nothing to f with get it fixed.

Not unsafe. Misfires are common. Clear the code and drive it. If it comes back immediately then change the obvious items- plugs, wires, ignition coil.

View Quote At last, somebody telling me what I wanted to hear. Going to fix it, they just can't do it until Thursday. Live 12 miles from town, so it's kind of a long walk to not drive it until then. |

Find an independent mechanic and get it looked at today. Sounds like plug(s.) The dealer will screw you over six ways from Sunday.

Came here to post this. The raw fuel from the misfiring cylinder is heating up your catalytic converter. Those aren't cheap. View Quote View All Quotes View All Quotes Quoted:

You will be fine. How many miles? Ever changed the plugs? Original plugs, just a tad under 100k. Replace plugs and wires. I prefer Bosch platinum +4 plugs. Magnicore wires. Then disconnect battery for 30 mins and try again (or reset codes with code puller). |

plugs
wires rotor dist cap will be about $75 total and 45 minutes of your time ETA: Also run a can of seafoam through it BEFORE you change your plugs. IT may smoke like a bitch for a few miles but that shit does wonders on old built up carbon. |

My jeep did the same thing. Was the wires shorting. When it's dark, lift the hood with it running. Do you see a spark from the wire grounding to the engine?

Plugs are good to go for 100K on most new cars, same for wires. So you put 100K a year on your car...that's some driving. View Quote View All Quotes View All Quotes Quoted:

Most likely be ok for a couple days.
On the other hand timing has the ability to completely wreck an engine, too. Like if your belt slips or breaks and you put a valve through a piston. |

No other codes to help pinpoint your problem? I would start with a basic tune up and go from there. |

My check engine light came on about 6 years ago, figure on fixing it when I get a round to it.

Timing belt?
Wife had her timing belt go out in her Chrysler product. Luckily, it decided to go out as soon as she parked her car at the apartment. Wouldn't turn over after that. Got it towed to a dealership and $900 later, it was working again. |

Go get a rental and get it fixed. Same thing happened to the 2005 TrailBlazer my mom had.

Regular old time copper or whatever plugs yes by all means change them often. |

I've been driving my ford ranger for the last 60,000 miles that way.

My '97 civic was throwing a misfire code when the headgasket failed.
Does the oil look like chocolate milk? |

It just acts like I'm not giving it enough gas up to 2,000 RPM. It sputters/wheezes. Going in Thursday at 8:00. I have to pick the kids up from school- no bus service today, so I don't have any choice but to drive it. |

OP if it ends up being a coil you can likely replace all of them yourself for what a dealer will charge to troubleshoot and replace one.

My bud has a Camry that was doing this. Turns out he had a bad coil pack that was preventing the plug from firing and just blowing unburned fuel out the tail pipe. Took about five minutes to swap it out.
