CHECK ENGINE light on Ford Ranger?

Question

I have a 1994 Ford Ranger and the Check Engine light keeps coming on while I accelerate quickly or drive up a hill. It goes off after I slow down. The truck runs fine otherwise. Any ideas?

Answer 1

Post the numbers from the check engine light, that will tell us a lot.

Answer 2

Go to Autozone and have them check the engine codes with their obd2 scanner. That should tell you what is wrong.

Answer 3

if it runs ok, then it,s probably the 02 sensor.

Answer 4

You will need to get a scanner and pull a code.  It will tell you whats wrong.  You didn't mention what engine size, but the 3.0 and 4.0 liter have 2 O2 sensors, I am not sure about the 4 cyclinders.

Answer 5

O2 sensor, but don't just change it. You need to check a lot of things. Fuel pressure, injectors, ignition. The O2 may go out of it's range due to a rich or lean mixture under load.  

Answer 6

you need to get the code. this web site will tell you how to get the code and what the code means
