Troublecode 186

what kind of repair do I need to make with a trouble code of 186 on a 93 Escort wagon with 1.9l? It sputters and accelerates poorly up to 30 mph. Thanks for any suggestions

The definition for code 186 is:

Injector pulse width higher than expected or Mass Air Flow Sensor signal voltage is lower than expected.

I'm not sure if cleaning the MAF would take care of your problem or not. If not you probably need a new one.
I was thinking a weak O2 sensor also. How many miles are on the car and how old is the O2 sensor.
