It's about my '92 240 station wagon.
Once in a while, especially after freeway drive, when I encounter some traffic or I am at a stop or in a situation where my car is idling in gear, the 'check engine' light comes on, to disappear when I push the petal. I need to add to that, that when this happens it feels as the car wants to stop.
Has anybody experienced this sort of problem or has any clue on what this problem might come from?
Thank you.

 

I think we took that light bulb out years ago. I would get a new cap and rotor and wires and look at your plugs if you haven't changed them in a long time.
