2001 Chevrolet Impala Repair Question
Chevrolet Impala Fuel pressure Problem
closed O2 sensor reading fluctuates between .050v and .800v approximately, is that normal, or a little lean?
What is the fuel pressure suppose to be?
Fuel pressure is 52 psi at idle, and 58 psi at a quick full throttle.
Can you get me a better diagram of the starting system. I think is one of those integrated PCM systems. Thanks
