Hi guys,

I am new here and do not own an rx8 its actaully for a friend of mine, basically everytime he gets on it WOT the car seems to bog down at around 6k and then is fine after wards, i have searched on here for a little bit but it doesnt make any noises as some members would call marbles, i dont know what it could be. Please help. THanks in advance.

 

Year and Mileage and Service History please

 

6250 is when the tertiary intake opens. A bog there could be a slow or sticking valve. Need more info.

 

Could be due to the rev limit when the engine is cold.

 

its an 04 with 60k miles and well maintained... recently started doing this and the check engine light turns on and off at times...we wait till the engine is warmed before we drive it.

 

Well does the CEL light ever flash at high rpms?

 

If it's throwing a code then head down to your local auto parts store and have them read it for you (unless you have a scanner yourself). Many places like Advance Auto Parts and Autozone will do it for free. Mine did that before the recall reflash of 2006. I had been trying in vain to get better fuel mileage by shifting at low rpms and setting the cruise at a party pooper 65mph. Hated every minute of it. For my pain I got 2 extra mpg and a gummed up top end with flashing CEls

1. Get the code checked
2. Use a good cleaner like Techron, BK44, Seafoam etc
3. If it's not too late and the carbon gets cleared out, drive it like you stole it, the way the Rotary gods intended.

 

thanks for the input guys i'll let him know

 

Its the revving limit when you barely start the vehicle. Its too cold so it wont let u rev up high as it is the same on mine when i found out. Same rpm limit just like his.

 

NOT. Read the post man. He's got a power loss issue with a CEL.

 

Have him post here.

A hersay problem is hard to come up with a solution.
