Greetings,
My 94 4L 4x4 Ranger (158K miles) failed the emission test today due to elevated NOX. The CHECK ENGINE light comes on after a few miles of driving.
My truck was never equipped with an ERG valve system. It does have the original catalytic converter. I'm going to replace it, as well as the fuel filler neck (small leak) and gas cap. The coolant level is ok so that isn't the cause.
Any other thought on how to get the truck to pass?
Thanks.
