Factors that affect fuel economy

I'll try what you said also GTP Dad, but I was also wondering if cleaning the intake like xeroinfinity said earlier (with the car running) would clean any more carbon out of the intake then just spraying it into the intake and moving the butterfly.

[xeroinfinity]

spraying into the intake while the car is running cleans deaper into the intake plus the valves.
Keeps the TB cleaner from pooling inside and diluting the oil, + fouling out the plugs. That always sucks

For the TB and butterfly, I use an old tooth brush soaked in TB cleaner, And on the Iac.

Hope that helps

Good advice xeroinfinity! I usually just remove the throttle body and clean as necessary. I have never had good luck with cleaning them on the car.

A bent tooth brush works even better
