Yes, you have 3 choices. Well, I guess you have 4.yodawill2000 wrote:If your KS is disconnected that's the problem.Your engine timing is retarded big time, By design.To relocate you will need a knock sensor AND the cable harness.Then there's no need to remove the old assy.The original Knock sensor is on the block below BOTH plenums. Major task to get too. Just ask Scott.
Reread his first post. You'll find the answer.ppastos wrote:What about the fuel filter, when was that changed?
If you know that your KS is unplugged, there is no need to look any further. THAT is your problem.mej30guy wrote:I guess the easiest way to attack this, is to know what I'm attacking. I'll wait to see what codes come up when I check the ECU.
Would a faulty MAF sensor cause this to happen as well? I cleaned it with the proper stuff on Saturday, and it ran like a top at the high end. The lag happened before the cleaning, too. (I did noticed that I badly need an alignment) But the high end was never a problem, it was always the low end lag.
All of them are not firing like they are suppose to be. The engine thinks you have crappy gas in there and that it is pinging/knocking like crazy. (Due to the KS being unplugged.) It retards the timing SEVERELY to keep the engine from knocking and self-destructing. The amount that it retards the timing is enuf that you not only feel a decrease in performance but actually think something is wrong with the engine.mej30guy wrote:Could some cylinders not be firing the way they should.
It's not a permanent fix. All you have to do is take the resistor back out. Relocated is better but you might want to try the resistor first.mej30guy wrote:I just read a "how-to" to go the resistor route. I didn't realize that it's basically a permanent fix. I'll opt for the re-routed ks instead.
Is the ks connector the red one that sits at the top middle of the engine, just in front of the firewall? I don't want to disconnect the EGR by mistake.
If your KS is disconnected you should find the end of the sub-harness that's connected to the KS and the corresponding empty ECM harness connector where you'll connect your new/relocated KS.mej30guy wrote:
Am I looking for a connector with nothing coming out of it? Those should be easy to spot, I would think.
RPMs at a stop are somewhere in the 1-1.2 area and quiet as a morgue.
You can be reasonably certain that the other end of the sub-harness is still connected to the KS itself and I believe the connection at the actual sensor is one of those u-shaped wire type connectors.mej30guy wrote:Saw the pictures, and I realized that I was staring at that thing all night! I just didn't know what it was. Looks like a snap to replace. Mine looked like it was hooked up at that point, and not hanging. Maybe the ks was disconnected at a lower point deeper in the engine. If not, how would one disconnect the ks without unplugging it from the connection at the top of the engine?
Do you need to manufacture a special bolt, compression washer, etc.? I saw on another post that the guy machined out a new bolt because the stock one was too short.
The RPMs I gave you were for sitting in park, not in drive with foot on the brake. I'll get that reading later.
In Park or in Drive with your foot on the brake?yodawill2000 wrote:Mines dead on 750 with the AC off.Something adjusted wrong ?
