Based on these readouts.. Engine Running Lean -Vacuum Leak-Engine Problems ...You have a Vacuum leak. I have used a windex type sprayer with plain water Here is a shabby video but it should give you the basics https://www.youtube.com/watch?v=MI2o9YNZ2Y0

Awesome , We will try it ! I'll let you know Thanks for the help appreciated:) Mahalo


Hi thanks for info - we tried no vacuum leak. Went to Dmv . Emission specislist there put car on machine. He says the code that is coming up is. P1128 Take to shop and fix . What does that code mean and what should be done to fix car?

Tom Harmon

This code is usually caused by a failing mass airflow sensor which would also cause poor gas mileage.

The MAF is usually located in between the Air Filter and the throttle
