Although with the IAD sensor plugged in and in drive the</p><p class=MsoNormal>> idle is not stable the engine RPM’s keep changing at every stop it’s</p><p class=MsoNormal>> different and I checked and the electric AAR is closed . It’s close to be</p><p class=MsoNormal>> called hunting just not as drastic. With everything plugged in the RPM</p><p class=MsoNormal>> drops 200 PRM and if I raise it adjusting the IAD bypass then it becomes</p><p class=MsoNormal>> unstable and can idle @ 800 RPM to 1,200 RPM. It seems there is a vacuum</p><p class=MsoNormal>> leak somewhere like the extra % of fuel the unplugged IAD temp sensor</p><p class=MsoNormal>> compensates for. Even when it’s warmed up with that sensor plugged it I can</p><p class=MsoNormal>> feel and hear this miss at the tail pipe , it’s not a steady miss like one</p><p class=MsoNormal>> cylinder would be it’s random as in it will miss once then I hear 3 misses</p><p class=MsoNormal>> . Without actually hearing it it’s difficult to put in words. It does not</p><p class=MsoNormal>> seem to be lack of ignition spark and if it is it might be the pertronix</p><p class=MsoNormal>> yet to me it is more like a lack of fuel . It’s a mystery why unplugging</p><p class=MsoNormal>> that sensor clears it all up in an instant. That sensors two wires do not</p><p class=MsoNormal>> have a short and the sensor reads what it should , it drops as it heats up</p><p class=MsoNormal>> and the readings are the same as they always were. Perhaps the sensor</p><p class=MsoNormal>> inside the IAD is covered in oil and is not getting the proper reading of</p><p class=MsoNormal>> the incoming air flow, all it needs is heat and it can get that just from</p><p class=MsoNormal>> the IAD’s temp , that’s just a guess. If I recall on older systems that</p><p class=MsoNormal>> sensor used oil temp , I thought I read that somewhere.</p><p class=MsoNormal>><o:p> </o:p></p><p class=MsoNormal>> William</p><p class=MsoNormal>><o:p> </o:p></p><p class=MsoNormal>> Sent from Mail for Windows 10</p><p class=MsoNormal>><o:p> </o:p></p><p class=MsoNormal>> From: Jim Adney</p><p class=MsoNormal>> Sent: Thursday, March 28, 2019 3:01 PM</p><p class=MsoNormal>> To: type3@vwtype3.org</p><p class=MsoNormal>> Subject: Re: [T3] On the subject of fuel senders and fuel gauge.
