Re: 2000 Ford Ranger 4 cylinder Runs Rough at 50 MPH
Buy a code scanner and try to catch pending codes. This can take out a lot of the guess work and save you a ton of money in the long run... hell, in the short run too!
So you didn't replace the front O2 sensor, just the back one, is that correct? Note that the back O2 sensor does not feed back to the ecu, it's more or less a dummy light.
Curious. Why did you replace the coils, and how much did they cost?
