The car started to die and bogg down intermittently. The gas pedal must be feathered to keep it running. Code po191 and two codes related to running rich have popped up. Can a fuel rail pressure sensor cause this problem or should I look elsewhere. Thanks, ej

 

Sounds like a fuel problem. You need to check fuel line pressure.
A fuel rail pressure sensor .....I like the idea .

 

either a fuel problem or air problem if it is running rich and fuel pressure is good check that your getting air no restrictions air filter plugged start with the easiest things

 

you stated that far better then I could have [sm=alcoholic.gif]
