Hello guys
I have 2003 Mazda rx8 with automatic transmission.
I am facing an issue after I have replaced its water seals. Car is missing a lot until it reaches 3000 rpm.
Iv CHNAGED plugs, coils, fuel pump, fuel injectors MAF sensor. Still the problem remains as such. Wiring n ecu has also been checked. Can any one help out in pointing rhe exact cause. Computer also shows no errors. Engine compression is 90 and 95. Throttle has also been cleaned.
Thanks.

 

90 and 95 what? And at what rpm? Compression is measured in 6 numbers @ 250 rpm.
What was done to replace the seals? They can't be replaced without fully disassembling the engine, did this problem right after the engine was reassembled?
Does it do this cold and hot, or only cold, or only hot?
Does it work fine after 3000rpm? Any other symptoms?

3500rpm is where the SSV valve opens, perhaps it's not fully closing. Google how to check the SSV for freedom of movement.
