Question:

Where is the slow gas leak that causes my engine light to come on?

I have a 2001 chrysler town and country mini van. My engine light came on when I had a 1/2 a tank of gas. I took it to a parts store to have them find out why the engine light came on. They said I had a small gas leak that could be from the gas cap not being tight enough. They turned off my engine light with their hand held machine. I tightened the gas cap and drove till I needed to fill up with gas and then the light came back on when it got to the 1/2 way mark again. What could be causing this problem? I made sure after I filled up again that I tightened the gas cap! This did not seem to help.

Answer:

First go back to the auto parts store and buy a new fuel cap and have them turn off the light again. If it comes on again, then someone who understands the fuel tank emission system needs to inspect the many hoses looking for the leak.
First try a new gas cap and have the light turned off again. If it comes back on, you probably have an evap leak. It's an emmisions related fault, you won't notice any problems, but its not something you can fix at home. Have to take it to a shop.
it is usually a deteriorated gas cap seal. Just replace your gas cap with a new one!
sorry but no your sycronizor is worn
You're probably looking at a tranny rebuild, dont waste money on additives, the damage is already done.
