Sounds like oxygen sensors.

Also sometimes the check lamp may come on and not log anything. Annoying i know.

 

[scottmcguinness172]

righteo should i just wait it out and see if the engine light stays on then diognose?

As above i agree oxygen sensors will be stuffed. You can new ones off ebay cheap, either bosch or delphi, just check to see weather yours are 2 wires or 4 wires, they run from the exhaust pipes on either side behind the engine.

Hey Scott,

I own a 94 VR and a month of two back I was coming home from Marshal Arts, and I noticed the engine light came on for a split second and turned off. All I had to do is pull over, turn my car off. Let it reset and turn it back on. What it is - is the car will pick up changes in the air fumes/sudden temp change etc, or if your towing a load and you give it some and its not responding properly etc. Also, it might be the injectors one may be loose and sending unburnt fuel out the back.

That's all I know on the subject.
Cheers.
Rare.

if the engine light is coming on there is a problem, if you have the problem while towing then obviously a sensor or engine part is failing under load and going out of spec tripping the engine light, it doesn't come on for no reason, personally i would look for the problem and fix it.
