Hey guys,
I was on a 3500 mile road trip recently and the car was great (2000). My service engine light came on at one point, but everything was running fine so I assumed it was an emissions related system and kept driving. 200 miles later it went off. Usually in my experience once an issue is detected, a code is set and the light stays on until cleared. Anyone have ideas off hand for a condition that could be intermittent and not store a code in memory? Does the old paper clip trick still work on the ALDL connector?

Thank you,
-Shawn

paper clip was last seen in the 93

go get it scanned to see what was up (autozone or other parts stores will scan for free)

Depending on the issue and testing frequency of that system the light can come on and go off on it'* own.

There will be a stored code that can be retrieved and it is suggested to do so, that way you can look into and possibly keep from having a spendy repair later on.
