Help have an 04 AT rx8 for the life of me, I cannot get the car to stay alive when im idling. If i get straight on the freeway and drive I can go up and down it all day , but as soon as i exit and im idle the car will sputter and shut down unless im gassing it while its in idle if i let it shut down I have to wait 15-20 minutes before it'll crank back up. I've changed the spark plugs, fuses, spark plug wires, new battery and the coolant is fine any other ideas to what could be causing the problem

 

have you cleaned your maf?
are the screens in the intake in place?
is your cat clogged?
fuel pump?
compression?

 

how many miles on the engine?

 

150k miles on it have not tried cleaning the maf will try soon as i get home. Screens appear to be fine but i'll also doublecheck appreciate the tips I'll post what i come up with

 

Vac leak? I found my vac lines to the oil injectors had hardened and then would pop off.

 

MAF was somewhat dirty I cleaned and same results screen is fine and any links on a diy for the vac lines no idea how to even check those

 

My car does the same thing. It is either bad cat or bad engine. I have gone through everything with my car and the dealer. Right now I am waiting for a new cat. I will see if that changes anything. My car will only stall at idle, after I have warmed it up for a while. Drives fine in the morning.

 

update finally getting a cel and im getting error p0301

 

Misfire - Have you checked the coils?

 

My car does the same exact thing. I ordered coils and I will be changing them this week when they arrive.

I think it might be my cat too so I bought an RP supercat but I am having a hell of a time gutting the cat. Anyone have any tips?

 

so i had a shop look at it that specializes in rotary engines they said my apex seals are worn out and I need a new engine does that sound about right? can't they just replace the seals?
