Engine Mechanical problem
1997 Chevy Blazer 6 cyl Two Wheel Drive Automatic 246000 miles
This is my wife's truck, she has had an issue with starting, she has to turn the key twice for it to start if it has been sitting overnight. (Fuel pump? Check Valve? Fuel Pressure Regulator?)
Yesturday she complained about a rough idle, in or out of gear it idles realy rough. Service engine light came on (I am not sure when) Error Code P0171, P0174 and P0300. Lean banks and Multiple Misfires.
I did check for Vacuum leaks and cleaned the MAS as well as replacing the Idle Air Control Valve today. Still idles rough like it is missing.
have the same problem?
