Hey there everyone, I've got an 89 toyota pickup with a 3.0 from I believe 93'. So I recently got a code 71 for the egr system. Truck still runs fine except at idle. It fine when I first start it up usually, but once it gets warm and I come to a light or stop sign the idle jumps up and down between about 800-1000 rpm. Any ideas as to what wrong here?

 

Don't guess. Your truck has already told you where the problem is. Just run the diagnostics. http://web.archive.org/web/201003261...77exhaustg.pdf

 

Thanks for the link scope103! I'll check all that stuff out and see what my problem was
