Coil plugs!!
Okay so I recently just got a 2007 Mazda RX8. My CEL started to blink and I asked my father (he gave it to me) and he said it was a misfire on one of the cylinders. Said that the reason why it’s misfiring is because his mechanic connected the coils in the wrong way. My question is, could that lead to a huge problem? |

Yes, yes that would lead to a huge problem to the tune of getting a new engine. Take it to someone who knows what they're doing.

Do we really need to explain how having the wrong injectors fire at the wrong time is bad?
But also, I don't think having your injectors miswired would cause misfires. Bring it to a specialist ir be ready to do proper troubleshooting yourself |

The wiring harness is made so that you cannot mix up the injector connectors. Has the upper intake manifold been off recently? A misfire is likely caused by an ignition fault. If you have not done so, replace your plugs, wires, and coils. A flashing check engine light is the result of a catalyst destroying misfire. As you can imagine this is a very bad thing.

My question is, could that lead to a huge problem? how many miles since coils and plugs were replaced? |

my father completely put an engine from a crashed out he bought, the crashed car had a good engine and I think it had around 80,000 miles on it. |
Ah so it has a replacement engine. That would have been good to know from the start.
Google "20 brake stomp procedure". This resets the ESS profile, which you usually want to do when installing a different engine. |

You didn't mess up the computer. Computers don't fail in that way. Do the 20 time brake pedal thing and then verify that the injectors are correctly connected and that the ignition coils are connected to the correct spark plugs. People have messed both of those things up while replacing engines.
