I just finished an install of a 2.8 in my 85. Had a bad vacuum leak with high idle. Found the problem. Was the vacuum hose under the throttle body. It started and sounded good, the first time. A new issue has popped up. It seems to still be idling a little high, not sure how high, think tach is off. I am guessing it is hunting between 1200 and 2000. This is the condition I have noticed on new to me engine. EGR has been blocked off. The set screw on throttle body has been tampered with and is in all the way. Along with this, I have not been able to drive car yet so the ecm has not been able to learn the new engine so I am hoping that driving it will do the trick. I still have to get the clutch working right and bleed every system. I was wondering if this could be just an ecm learning issue. My old engine had the egr.
Thanks for any opinions.

The ECM expects that there is an EGR system on the car, and the only way around that is to re-program the ECM.

If your throttle body set screw has been changed, who knows if you have another vacuum leak or not. There is a procedure to get that throttle screw set right....I think it is in the Ogre's Cave.

I have my egr from old engine so i will inspect the tube and if it's good will install it. I looked at the set screw procedure and will attempt that. thanks for the advice.
