Another P2187 and P2177 thread
Yeah.... this again.
The car is rather new to me, and Im determined to get this friggin thing running without issues.
So my car runs great....... cold start it idles really rough though, once it warms up it is fine but of course with these awesome errors.
This is what I have done so far
-replace valve cover gasket
-Purge solenoid replaced - although mine is a squared one compared to what one company sent me and everyone seems to have.
-Throttle body cleaned
-replacement fuel cap is on the way the one on the car doesnt seem to really tighten
Not sure hot to check for leaks at home... the hoses look to be ok and nothing sticks out. I have that EONON radio with the OBD scanner piece but I dont know if it's giving me realtime fuel data to do an analysis.
This is what I have been able to piece together by doing countless searches. Does the rough idle at cold start point to anything in particular from this list?
These codes will come on if the same condition is seen for two consecutive starting cycles.
P2177 = Fuel system too lean at off idle
P2187 = Fuel system too lean at idle
List of possible causes for both codes:
Front HO2s deterioration
Front HO2s Heater malfunction
MAF sensor malfunction
Pressure regulator (built-in fuel injection pump) malfunction
Fuel pump malfunction
Fuel filter clogged or restricted
Fuel leakage on fuel line from fuel delivery pipe and fuel pump
Leakage exhaust system
Purge solenoid valve malfunction
Purge solenoid hoses improper connection
Air suction in intake air system
Insufficient engine compression
Variable valve timing control system improper operation
No siggy needed.
