Hi all. You may know that I have my car back to running order now. But...when the bypass wire that you unplug to set timing is plugged in, there is a knock. I unplug that wire and the knocking goes away. Is this knock sensor related?
Thanks

 

What did you set your base timing?

 

6* BTDC

 

Strange. By plugging in the bypass wire the ECM will advance the timing. If you have a stock PROM in the ECM it should not be knocking... Are you running low octane fuel?

Or try this, set the Base timing to 0 deg. just for a test and see if it still knocks when you plug in the wire.

 

Tried it, same thing. The last time I filled up I put 91 octane in.

 

No more ideas.? Guess I'll start throwing money at sensors. Probably a ECU will be first. This thing is really starting to bug me!!!

 

OK, so I am an idiot. I went back out and rechecked my timing. It was set at 6* ATDC, hence the ping. So I unplug it and set the timing to 6* BTDC, no more ping. BUT>>>>>>>................. now it runs like total A$$. I give it a little gas, and it sounds like the bottom end is going to explode with a bunch of jumping and knocking. It idles fine! And when I shut it down it won't fire right back up. But with my *** backwards timing, it rode and drove and started fine. Just didn't have much power. What am I overlooking here? Please help!!!

 

TTT

 

So, I have tried it a 0*, 2*BTDC, 4*BTDC, 6*, 8*, 10*, and so on. Nothing changes in the miss and jumping. I have checked all my plug wires, put in new coil, rotor, cap, and ICM. I have even tried putting it back to the 6* ATDC (where it was before ). Still nothing. I figured I could put it back to running order atleast. But now it spits and sputters, knocks and jumps no matter what.

BTW, it has no more knock or ping!!!! WEIRD
