I'm thinking of replacing my motor in my 99 Ranger 4.0 but have a couple of questions. To start with, the existing motor is a used motor with a label that says 2000 EXPL, so I assume a previous owner replaced the original motor.
Car-Part.com shows four options based on emissions standards including whether the engine has or doesn't have an EGR valve.
The sticker in the engine compartment indicates the truck was built to CA emission standards and the non-original motor does not have an EGR valve.
Here's the questions: If the original motor DID have an EGR valve, could the lack of an EGR valve be the source of my P0171 lean code? Is there any way to determine from the VIN whether the original engine had an EGR valve or not? Since I know that the original engine was CA emissions compliant, would I be OK with either engine with or without an EGR valve, as long as I get a CA compliant engine?
Although I am dealing with that pesky P0171 code a motor swap seems inevitable due to severe oil usage, both burning and leaking.
