Just replaced my head gaskets and put my 87GN back together. When I took it for a test drive it drove good for about 2 miles then just fell on its face everytime I would give it any gas, was able to idle it home. Idles ok when its cold and then will start to idle crappy and die. I cant find any vacuum leaks, and it is pulling a code 33 (mass air flow sensor high) I have ordered a new LT1 maf but just want to see if there are any ideas you guys might have.
