Ah, yes…the New Year’s Resolution. That great idea for personal improvement that looked so attainable when you wrote it down on January 1st, but is already crumpled and neglected on the floor next to your bed.

We’ve all been there. Some resolutions are impossible to keep because they are simply not realistic. We all want to win the Daytona 500 this year, but something tells us that just won’t happen.

Other resolutions fall by the wayside because we simply don’t have the knowledge to make the change. You might resolve to make your home more energy efficient, but you don’t know how to install double-paned windows. You might resolve to take better care of your car, but you’re not a mechanic. You just want to get your car running like it used to and not spend heaps of time and money trying to figure out why it doesn’t.

Let Pat Goss help with some free advice from America’s Most Trusted Mechanic. In this video, Pat reveals the most common cause for lackluster acceleration and engine performance.

Now that you are armed with that knowledge, you are a step closer to keeping at least one of your New Year’s Resolutions. As for winning at Daytona…we’ll leave that one up to you.

Happy New Year’s from CARCHEX, wishing you all the best in 2012!

You have questions. Pat Goss has answers.

My car doesn’t have the “getup-and-go” it once did. What might cause this?

One of the most common causes of poor performance, in other words lackluster acceleration in a car that has a few miles on it, is going to be the mass airflow sensor. That’s the part that tells the computer how much air is going into the engine and the computer mixes fuel at the proper ratio to that air.

Well, if it under reports the air, then you don’t get enough fuel for proper acceleration. It does not set a code in most cases. It does not turn on the check engine light. The engine just doesn’t run like it should. So check the numbers on the mass airflow sensor.
