I did this because if it was plugged in the engine struggled between 1000 RPM and 2200 RPM if it was in park. By struggle I mean the rpm was not a smooth climb it would sort of hang and drop between the rpm range above. It also had a miss fire at idle , not a back fire but an erratic miss . <div><br></div><div> When I drove it I didn't feel any miss yet heard slight popping out the exhaust when I let off the gas.</div><div><br></div><div> I know the right Empi header to the right heat exchanger leaks I can hear and feel this and that may be the popping I hear . ON that miss i can't imagine that is related to the exhaust leak and I saw this because it's been leaking there for 20 years and didn't have that erratic miss or struggle between those RPM ranges . </div><div><br></div><div> I know it has the proper ECU and throttle switch and pressure sensor since Jim provided that info. I also checked every engine ground and redid all and that seemed to help for a while then it was right back doing this. I also know all a vacuum leak really does is allow more air and as far as I know does not make for a richer mixture unless the leak is at the intake gaskets and injector seals . I do know all for runner short hoses are oily , I have new ones yet not the intake gaskets . </div><div><br></div><div> I have read one can replace the paper on the intake spacer . I thought of pushing back the old oily short hoses and removing the IAD without removing the runners . It's possible yet does not look easy . </div><div><br></div><div> Basically what I'm asking is should I repair the exhaust leak first then see and it this doesn't help go for the short hoses and replace all the vacuum lines off the IAD . If I could get two FI intake spacer/gaskets I would go that route . I don't think the old ones are cracked and may be able to just make new paper gaskets. </div><div><br></div><div>William</div></div><div id="m_-7606848137247113864DAB4FAD8-2DD7-40BB-A1B8-4E2AA1F9FDF2"><br>
