NO power

[Tomas_St]

what kind of problem can be. my mr2 does not accept the accelerator. car does not pull, after reaching 3-4k REV. When the release of the accelerator gently, the power is back slowly , just need to find that point on accelerator . The ECU shows 21 error code. but there probably FCD problem is on that code

also from exhaust come noise. similar as launch control as delay ignition or something cant enplane

o2 sensor been replaced

Error code 21 is Oxygen Sensor Signal.

The problems you're describing sound like the knock sensor is dead. Have you reset the ECU since replacing the O2 sensor?
