Huh,went to test my alky,but can't.My truck is hitting 18 degrees KR as soon as I touch the gas(with the alky OFF).The knock count is also cycling like the 02 would.I know it's not really knocking (I put in new plugs today and the old ones looked new)I can be sitting in park idling and hit the gas the KR maxxes out.Any ideas?

Re: Stupid KR

Ha ha ****ers.

Let me clarify it.The knock count isn't going up,it's cycling like 35,110,235,35,110,235.

Just looking for a little practical advice... :D

Re: Stupid KR

Couple of oddities for me over the years that caused gobs of KR......

- Loose/Loosening ECM grounds
- Faulty/Failing ECM
- Rattling components
- Bad reprogram of EPROM (wouldn't just arise outta the blue though)

And then the normal things......

- Advanced physical timing
- Bad knock sensor
- Bad ignition module
- FP way too low
- Failing fuel pump

When we finished up the '92 Syclone it had 6-8 deg of KR at 1 psi......I chased it down to a combo of advanced timing, rattling fuel lines, AND dirty injectors. It was evident when no amount of FP adjustment would help. Set timing properly and a little better......tightened loose fuel line clamp and a little better (still too much knock @ 10+ psi).......finally, changed injectors and all has been beautiful.

Re: Stupid KR

Something else to check... there's a body strap on the driver's side of the engine that straps the engine to the frame. Unbolt that and see if you still get KR.

Your describing is an engine tie down that someone added.

Re: Stupid KR

Sorry to walk on your post here but I have a ? for HOOD about the fuel line thing. Mine arent bolted down near the T-Case. Are they supposed to be? I noticed two bolt holes on top of the T-Case that accept pretty thinck bolts and there is a bracket on the lines that look they are supposed to go there but they dont reach it at all, they are about 1/4" off with me trying to force them. I know about the little 10mm ones and they pretty much match right up.

Those two big holes on the top of the transfer case bracket are where the transfer case to transmission brace is supposed to be... The fuel lines are held in place with that single 10MM bolt.

Re: Stupid KR

Jimmy, could be that the chip is not fully seated. I had the same issue two years ago. I was getting 18 degs. of knock at 5% throttle. Took the chip out and reinstalled then all was well.
