The socket is forward so the plug on the left are the passenger side bank 2-4-6-8-10. Note they ate all black while the driver side bank of plugs are not.

Got a p0174 code as well. Changed plugs, wires, map sensor, pcv last night. Checked vacuumed lines with brake cleaner and looked good, no leaks

This all started bc my gas mileage, a solid 9mpg dropped to four and she ran like crap, exhaust smelled like a 72 Nova, missing.

Oh, fuel pressure at 46-48

Any thoughts?

Thanks guys.

John.

 

Do you have two front O2 sensors in there? (one for each bank?) If so, replace the passenger side sensor.

 

I agree, pass side O2 sensor isn't sending proper info. Since you're doing one, might as well do both.

 

Just did. Good call she runs great hauled the boat and ran her 50 miles, 8.7 mpg avg! How sad is that -I'm happy about above 8? Oh we'll, thanks fellas.

John out.
