yo RICKY!:thumbupWell done Miesk. Now then, have we ever ascertained that they were actually needed or really did anything on our pre-OBDII trucks?....
Thanks for the info Seattle, I am getting no codes, just pings any time under load and I am just trying to rule out all of the possibilities. I will try testing to see if the timing changes when I tap on it with a hammer.Have you checked for OBD-I codes? If your Knock Sensor or associated wiring is bad you should get a KOER Code 25 (Knock not sensed during dynamic response test). Likewise, the 3-digit code is 225.
Testing would involve simulating operating conditions by connecting a timing light, starting the engine and tapping the manifold next to the Knock Sensor with a hammer. You should observe the timing retard momentarily.
If there is no response, turn the engine off with key on and check the harness connector for 5.0v reference voltage. Check for a wiring short if required.
If you need to replace the Knock Sensor, I believe that OEM is color coded to ensure the correct frequency on specific engines. I have read about Mint Green, Dark Blue and Yellow coded sensors. But having a 5.8L/6.7L, I cannot tell what color code you should have as I do not have one.
FWIW, I believe that Ford only placed them on older Trucks and Vans, although I do see them listed for the newer modular engine Trucks and Vans as well.
I have a pinging problem that I have been trying to fix ever since I owned the bronco, I wish I could set it at 13 and forget about it, but it would rattle like crazy, I am at 8 now and still ping when under load. it would be great to just be at the stock 10.Am I missing something here, why can't you just "manually" turn the distributor and advance the timing to 13* with the engine running, what's the issue...?
Good Luck ~ :thumbup
This sounds bigger that just your Knock Sensor as it pings throughout the timing advance. I would also look at your fuel system, ICM and Distributor.I have a pinging problem that I have been trying to fix ever since I owned the bronco, I wish I could set it at 13 and forget about it, but it would rattle like crazy, I am at 8 now and still ping when under load. it would be great to just be at the stock 10.
