check engine soon light

[keildl]

I have the same car, but not the same problem. My problem has always been with the fuel injectors getting clogged and having to have the spark plugs cleaned and recapped (3 times between 40K and 125K). Anyways, if the mechanic can't find anything wrong, take it to someone else or consider that the sensor could be bad. I am tired of hearing that crap that the gas cap may not be on tight. Are they charging you to check the code and see why the check engine light is on? Autozone does it for free as long as the check engine light is on when they hook up the code reader.... By the way, you can reset all the codes by simply disconnecting the battery and reconnecting it.

I have a 99 Monte LS the only time the light comes on is when i fill up and go on the expressway. I have had it checked and the code is 1870, transmission component slipping, but when I had it checked at the mechanic he could find nothing. It has happened 3 times the exact same way and never in between, and it never comes back on until the same situation as above. Could it be still reading an old code problem that has been fixed or just the gas cap not tight enough???
Any advice out ther??
Thank you

I have had to pay twice for the car to be checked. But since the light has gone off by itself after a while by itself, I haven't taken it anywhere else. I would be tempted to have it checked if the it wasn't running good, but really, there doesn't seem to be anything different about the way it drives at all.I did have it turned off at Autozone, thankfully there is one in this small town!! Thanks for the info on the battery thing, though, that something I didn't know.

No problem. Disconnecting the battery only clears the codes out; the light could pop back on again if the sensor detects something wrong.

Your right about that!! I will have it checked at a transmission shop here and hopefully they don't find anything or, as suggested, valve repair.
I just have to be careful who I take it to.
Thanks.
