Hey guys, its been a while since I've been on the board hope everybody is doing well. I've got an 86 GN 93000 miles with an old Hypertech chip ( I know) Walbro 340 and adj. fpr. I'm getting 35 degrees of knock retard at idle and was wondering if I might have a bad knock sensor or could it be something else. Btw o2 checks fine TPS is good and BLM is ballpark. Any help would be greatly appreciated :dunno: .
The car still runs with 35deg KR? When I got that much KR at idle the car would just stall. Turned out my maf pipe was touching the alternator pulley at idle.HTH
I'm using a Mac Tools Taskmaster for my scantool. Steve when I unplugged the knock sensor the idle began to drop towards a stall until I plugged it back up. There's anything other than WOT? :headbang: I don't think I'm actually getting that much retard the car is pulling too hard. Faulty reading or incompatible scantool :dunno: .
when I used my Auto Xray scan tool it would put my car into limp mode and it would show 35* of knock retard...but car ran fine and would show no codes....some scan tools do not work...which is why I have a scan master DS and PL...could just be the scan tool
