Default Mysterious Service Engine Light

This is on a '96 LT1. Service engine light came on and stayed on two days and 60 miles, then went out. I thought it stayed on until the problem was fixed and the light was reset. So, does the light go out and the problem remain, or if the problem resolves itself does the light go out. I had just ran a bottle of techron through the tank and refilled it, so maybe that had something to do with it?

The DTC should still be stored. All you need is a paperclip!

You have an OBD11 computer. Go to fleaBay and get for $19.95 a OBD11 code reader. It come with a manual and an explanation of all codes and will also erase those stored codes. It has saved me much time and with a factory service manual, it will save you tons of money.

If the light is out, it has resolved itself, not saying it wont come back on. You may want to read the code, to see what it was.

OBD I uses the paperclip method, OBD II needs a code reader ('96 and newer vehicles).

Advance or AutoZone will read your codes for you or let you borrow their reader.

Get the code for free and then order your own scan-a-ma-jig.

Good information you guys. Thanks. There is an Autozone down on the corner from me, and I will go see if I can use their code reader. I may check on E-Bay for a reader also. Thanks again.

AutoZone will also give you a freebie code-reader key ring. I keep mine in my console for when it comes time to check codes.
