Agrivating story.

Once upon a time a man bought a PT cruizer. He thought hed be awesome and drop in a K&N air filter and reset his computer by unplugging the battery. On his first test drive he marvled at the improved performance. Later that same day he noticed that he ALREADY needed more gas. With the use of a local Grocery Store calculator ( the ones on the handle of the cart) he figured out that his GPM had gone from an acceptable 19gpm to a frightening 10gpm. Kiniption fit dosent begin to describe what happened at that point.

After he calmed down and thought out what had happened.

Any Guesses?

When he first drove on the freshly reset computer, he did nothing but mash on the fast pedal and taught the computer that efficiency was not important. So, he reset again and was nice to the car for the next 200 miles. Now, he gets 26 mpg.

Sounds to me like your right foot is getting a little heavy. Perhaps you're putting it to the floor a bit too often? Even going all the way to the floor every couple of accelerations shouldn't drop you down to 10mpg. It's probably the grocery store calculator that's giving you the problems.

Luckily the problem is solved now. But it was no joke, i had taught the computer that MPG was no issure so it was opening it wide up all the time. I had to reset the computer again to fix it. Lesson Learned!

Are you sure you didn't just miscalculate based on the fact that when you disconnect the battery for a few minutes your trip mileage is reset? That is an enormous swing just from a computer reset, don't you think? I mean, if the computer thinks you're driving flat out all the time and dumping all that fuel in, wouldn't you expect to feel a big jump in power too? And we all know that doesn't happen, or those who have tried it at the racetrack would see huge improvements in 1/4 mile times, but in fact they don't.

Yeah, thr tripodometer resets.
Heh, even know I knew it, it still threw me a loop when I checked and saw my mileage for the tank was so low.

Ditto. I did the same thing a few weeks ago.
