2004 Mazda Rx-8 Rough Idle/ Acceleration at 3k makes loud errr sound

Deflooded my 04 RX8 in August.

Ran like crap.

Brought it home, fixed a few things.

seafoamed the car.

fixed coolant leak.

car now runs. But only with a jump start.

Idle is rough.

When accelerating the car a loud *BREEERRRRR* sound at 3,000 rpm line, everything below 3k rpm line like car before it was flooded.

can drive the car at a top speed of maybe 60 mph but not anymore that that. Car varies from wanting to die at idle, to being just fine and dandy.

First thing if its an engine related problem is to always compression test to rule out the engine as a problem. If that's not it, replace coils, plugs, starter and wires if you return good compression numbers.
