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.

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.

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?

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.

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. Troubleshooting vehicles isn't that hard a lot of times. Aren't Jeeps notorious for bad camshaft timing sensors? No other codes to help pinpoint your problem? I would start with a basic tune up and go from there. |

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. |

Pop quiz hotshot, there's a misfire in your Jeep. Once the Jeep goes above 2k rpm the engine is armed. If the Jeep drops below 2k rpm, the Jeep blows up. What do you do? What do you do? |

I have to pick the kids up from school- no bus service today, so I don't have any choice but to drive it. |

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.
