4AGZE power loss above 6k rpm

Post by BIGBOBO »

Is it normal for a 4AGZE to suddenly lose all power around 6200 rpm?

Engine is from an early AFM MR2, is completely stock and runs fine. Plugs, wires, distributor cap and rotor were replaced recently.

Of course it's not normal.

More info required, have you looked at fault codes etcetera?

Problem has been resolved by replacing the oxygen sensor. Car was running extremely rich and failed emission testing.

Now pulls happily to 7k.
