I started getting eratic knock the other day. Mainly in the first 10 min of driving. Big knock spikes or locking at 43 counts. All at light acceleration. Mash the throttle...no knock. After the 10 min, it acts normaly.
So after talking to NCgalant we suspect the knock sensor is going bad. It's of unknown vintage, got it when my other one melted to sealant out of it. So it takes me 2 hours to get to the damn thing and it looks fine. Nothing's melted. I suppose it could be bad inside. I order one from Advance and it should be here tomorrow. My questions: 1--anybody experience something similiar? 2--the sensor is a GP sorenson (sp?) the guy at Advance said he thought it came with just a pigtail. Do the colors match the stock connector, so I just have to splice it together. Or do I have to dig up a schematic from somewhere? -------------------- 92 Eagle Talon TSI AWD "The Black Golfball" How fast can a 14B go???

Huh...Sorry to pull this thread up but one year later and I have the same problem pop up!
Huge random knock below 3000 rpm just tooling down the road, WOT is golden. I had Nathan reburn me a chip modified to try to ignore the knock before it goes into boost, but it still remains. I wondering if I've got some lifters going bad and bleeding down causing enough racket to set off the knock sensor. I pulled off the valve cover and a few looked more compressed than the others. I guess under higher rpm (WOT) the oil pressure could keep them pumped up and quiet and not set off the knock sensor. I'll probably call Mitsu and see how much an OEM knock sensor is, it's got a year old GP sorenson in it. Anybody know of a good place to get the 3G lifters? I remember reading that they are better for lifter tick. Comments? -------------------- 92 Eagle Talon TSI AWD "The Black Golfball" How fast can a 14B go???
