Corrado low miles per gallon


Recommended Posts

Hello again,

 

You replied to my question in November about my VR6 low mileage. After the engine has been running for about 10 mins the car has slow acceleration at low revs in each gear and then it works as usual at higher revs. I think vacuum leaks, spark plugs or wires would affect the running at all revs? How can I tell if it's O2 sensor causing the low mpg because there were no error messages when the laptop was plugged in looking for all faults?
