I dont know the correct place to put this so if it needs to be moved, please do. I am hoping that someone in the Rx8 community has a set of known working stock ignition coils that they would be willing to send out so I can test to see if that is my problem. Problem is hard starting only when cold, and major spitting/sputtering at high rpm. Once it starts it runs flawlessly until you rev it up high (no load) and it starts to sputter. I feel like it is ignition, but would rather be 100% sure before I drop that kind of money on parts. So if anyone has abd would be willing to loan out a set of known working stock coils, please let me know.

TL;DR. Looking for a set of stock ignition coils that are known good to either confirm or rule out bad coils as the cause for the issues I am facing. Prefer to borrow and return once testing is done, but willing to work out a deal.

 

I have. But if it was the coolant seal I would/should see coolant on the plugs and in the exhaust. But all I'm getting is fuel. Remember, this is the one you and I emailed back and forth about thinking it may be injector drivers going bad. I have a gut feeling that the coils are bad. Would make sense because it only starts hard when cold, when there is more fuel to ignite. When hot it starts perfectly. But the other major clue towards coils is the spitting/sputtering when revving it above 4000 rpm. But I want to be 100% sure its ignition before I drop money on your upgrade kit. If it is coils, Id rather upgrade to a better setup than to have to repeat this process in a year, know what I mean?

 

Have a set of D585 coils with harness and plug wires I can send you

 

Are they known good? Reason I ask is because I had built a ls coil kit using ebay coils and didnt notice a difference. But that was before I did the carbon clean, fuel pump, and other fixes. And they are ebay coils so probably not right anyways.

​​​​​Are you cool with sending them out for me to test with and then me sending them back to you when I get a result?

 

Well I suppose some people are beyond help. Good luck.

 

Look, for all I know the fact that I got the kit off ebay is why it didnt work. If you are willing to send me a set to test with I definitely appreciate it. At this point I am willing to try anything. And I have already been burned once "thinking" I had the right part but it ended up being wrong. I mean it took a used pump and then a failed high output pump before I bought a new fuel pump assembly from Advanced. So, if you are still willing to help, I would be extremely grateful.
