Geo 1.0 and 1.3l like yours plug up a lot. Simply take the valve off and clean it and the ports it uses to route the vacuum and exhaust gas.
well on my 2000 Chevy tracker it is an egr flow malfunction. Girl at autozone said it could be a egr blockage.... Mike
I am having the same problem, so far, I have found the code refers the the EGR System. I will post more about what I find out.
Remove the egr valve from the tracker. The valve can be soaked with carburetor cleaner, to loosen stuck material, Wipe out loose build up, then wash with carburetor and allow to air dry. Re install the now cleaned valve.
AnswerIt's under the EGR modular. The EGR modular is on the top of the engine on the passangers side close to the fire wall and looks like a black hockey puck. Follow the very short vaccum line off of it to the EGR valve. 2 hoses run to the EGR switch and the bottom 1 runs to the EGR valve.

The 1991 Geo Metro EGR valve can be located on the air cleaner housing. The valve will be on the back of the housing.
After replacing the EGR valve, use the diagnostic tool and erase codes then read the codes again. I had the same problem on my 97 geo metro. After replacing the egr valve, the check engine light stayed on. After a while it was suppose to clear itself but it didn't. So I went to autozone borrowed their diagnostic tool, erased the codes and then my car passed and the check engine light went off.
