Ot exhaust leak before the o2 sensor

[Mike]

I am working on an 01 navigator with the same issue…i will look into this as well because he had the engine rebuilt recently…thats when the p0171 code started.

[Mike]

Sounds normal to me

[Mike]

Did you charge the high side or low side.

[Mike]

I dont see how the tps would cause high co

[Mike]

Correct…but i dont see how it would cause unburnt fuel.

[Mike]

Yes….or a shorted load device…you need to look at the wiring diagram

[Mike]

Ya…a pilot bushing…is it still in good condition?

[Mike]

The picture with the clutch disc sitting on the pressure plate…is that how you had it installed on the engine? If so, the clutch disc was installed backwards…the springs are supposed to face away from the engine, not towards.

+1 on impact

[Mike]

What’s the code?

[Mike]

If you dont have access to a smoke machine then start by following all evap hoses and see if you find the leak.

[Mike]

3 ft breaker bar

Tire cupping is also a sign of warn struts
