I've got a 91 EF8 that flickers a warning light at around 7900 RPM. I have included a picture below with the handy square outline.

Anyone know what this light is?

 

check for codes. could be for a misfire

 

As far as I can tell it may be a catalytic converter warning light? Can anyone confirm this?

Thanks alot man! I will get on that, any reccomendations for replacement?

 

just buy a piece of tube the length and diameter you need and weld the flanges on. cheap and easy.

What about the temp sensor that is currently in the stock cat?

 

any exhaust place could weld a bung to the test pipe and screw it back in.

 

think of it as a shift light

 

Thats what I said on another forum! haha

My ZC cluster has the same pic but it is my shift light/engine light.
