Hi everyone my rx8 is struggling with hot starts, I had it diagnosed and it needed plugs coils and leads which I replaced (these did help alot) but the problem still persists...

Had a compression test and numerous other tests and there all fine. Any ideas what else could be the problem? It's a 2004 192bhp

Any help would be great

is your starter motor speed up to spec ?https://www.rx8club.com/trouble-shoo...ck-out-207244/

I'm not sure how can I find out? I'm guessing with it being 2004 it's got the old weaker starter?

Why would I only be having problems with hot starts though and not cold ones?


Il check the link out, thanks

Also if I rev to 3000 for 10 seconds and turn off this completely gets rid of the problem and a hot start is fine? But don't wanna be doing this everytime lol

Check your fuel pump and catalytic converter as well as your maf.
Compression specs?

possibly soak in ... sea foam for you!

I dnt have compression spec although I know it was good lol

Is seafoam only needed for low compression though?


How can I check fuel pump and maf?

There's a service manual on foxed.ca, use it as a reference for the fuel pump.

Let a specialist do a compression test and come back with the proper results. "good" isn't enough to rule low compression out.

The maf can be cleaned. Google rx8 maf cleaning.

seafoam combats carbon build up.

It was done by a professional and compression was good? I don't have a printout? And ok cheers il look it up how can I know if its my starter?

Is this worth doing? How do I go about doing it?
