I am 2010 rx-8 r3 owner and i am new here. I need a help. After rebuilt the engin there is a problem. Sometimes cel is blinking. P0301 and P0661 fault codes were shown two times. Plugs and coils are New also. And i drive carefully i dont reach 4.000 RPM until 1500 km. (Now 900 km After rebuilt) hot and cold start are perfect . No smoke no vibration etc. But acceleration isnt Good enough. How can i solve the problem ? Thanks

Are the wires new and connected correctly?

P0661 is supposedly SSV problem. Check the solenoid and see if it's opening correctly.

Is your catalytic converter okay?

Wires are not New but connected correctly i suppose

When catalytic converter is cloged , removed it-
now catless
