Hello from Australia guys.
I recently had the check light on with code P0172 running rich.
I have check so far many things and i can’t work it out. I’ve changed spurk plugs and coils cause they’re old. Check with the specs map sensor and also adjust valves too. I’ve inspect on every intake gasket or pipe with throttle cleaner to see for vacuum leak but nothing. I’ve also cleaned the egr but was pretty clean. I’m connecting the car with the obd2 and check for short trim and im running always from -10% to -18%. Of course not to.mention that driving around for work, best i can get from the computer trip is 14 litres per 100kms that is very high for that car. Any idea or anyone had similar problems?
Thank you very much.
