Surge at idle

Hi all.

The problem I'm having is a rapid 100 rpm fluctuation at idle.

uhn-da-uhn-da-uhn-da-uhn-da...

The weird part is that it doesn't do it all the time. Usually occurs when the engine is warmed up though, never when cold.

 

Any ideas?

 

oh..it's an 89 GL 4x4 wagon with the EA82 not fuel injection. Runs great other than that.

Thanks!

Sounds like EGR valve to me. You can block it off and see.

 

Cool! I'll give it a try.

Thanks!
