Changed coils, lost power!?
I have an '09 R3 with 48k, and I know a lot of members suggest that coils, wires and plugs need to be replaced on regular basis ~30k (miles). As a result I replaced the coils at a dealership and an order was placed for ignition wires. I was thinking of changing the plugs as well soon.
However, after the coils were changed the car starts little weird, I can upload a video, and from 3-5k rpms I can feel 10-15hp loss of power. Any ideas what might be the case? |
You have an accurate butt dyno lol, my best guess is that the wires aren't fully connected.
|
Recheck all of the connections. Make sure everything is bolted down to the required torque and leading to the correct coil/plug, and make sure all wires are snug (hear a click).
|
what specs do the coils need to be bolted down to i just tightened them till i couldnt manually turn it anymore.
Having power loss issues as well after 5k and weird screaming noise check it out https://www.rx8club.com/rx-8-discuss...cluded-245758/ Sorry for the threadjack Filip could i thought we could be having the same issues. |

Thanks bro. Im gonna gut it soon or i find a midpipe i might just swap it.
Quick question .. when you gutted yours im assuming it through a CEL right ?? And emissions wont be passed with it gutted ? |
OMG! You are not gonna believe it. I opened the hood to check everything and they forgot to put on coil. So there is only 3 connected. And yes paimon.soror, I did it at Westowne Mazda (427/dundas).
Now, I'm not really good with mechanics, but is it ok to drive it like that to the dealership which is like 8km away from my house? |

What isn't connected on the 4th? If it's at the wiring harness end, then yes, technically you can, although it's not great for the engine.
If it's a plug wire not connected, the coil will fry fast. Give them a call first. Either way, both are REALLY easy to connect. |
