EGR code, could it mean bad IMG

instead?

The code is P0401 stating EGR flow insufficient, but I've heard other's saying the rough idling symptoms could also be a bad/leaking intake manifold gasket.

Is it possible the code is not related toward the EGR, or are the codes pretty honest?

Nope I think you are correct. That is a possiblity too.

If you are getting an EGR code, it is EGR system related. If you had a vacuum leak massive enough to prevent EGR flow, your 3.2L would run horrible, if at all.

Cool ok, thanks.

No it's definitely running fine, idle is steady at 750 rpm just a tad rough though.

I'll re-clean the EGR and check all the connections and go from there.

Thanks!

I had the same exact trouble code/problem with my 1996 Rodeo (118K miles). The EGR opening at the intake plentum was almost completely closed with carbon buildup.

To fix this problem, you have to unbolt the EGR valve and small aluminum adapter from the intake plentum, and scrape all of the carbon buildup from the EGR opening in the intake plentum and adapter.

When you are ready to do this, have someone turn on a canister vac and hold it near the EGR opening of the intake plentum while you scrape the carbon buildup. This way none of the carbon will fall into the intake. Finally, re-attach the EGR valve and adapter with new gaskets, and you are done.

Oh, don't forget to erase the trouble codes by disconnecting the battery for a few minutes. Good luck.
