I got a 94 Celica st 1.8L okay so the problem I'm having the car runs fine until the check engine light comes on.as soon as the light comes on the car does not want to accelerate fast it's almost like it puts it in limp mode I jumped the ECU and it popped up codes 5 and 2. supposedly 5 is oxygen sensor and 2 is air flow meter signal. I know I have an exhaust leak between the two oxygen sensors would that be causing it to do this please help.

You can use the probes on a multimeter to measure the voltage of the O2 sensor via the diagnostic port under the hood. The same is true for the map sensor.
