I pulled out of my friends place today and gunned it and the car fell on its face. 0.0KR at WOT but only 5.0 degrees of timing!
WTF?! I get up to 30 and slam it again, maybe 7.0 degrees of timing and still 0.0KR. Ok wtf now for real! We go see a movie, get out and on the way out I floor it. Got 14.5 timing and still 0.0KR due to the cool engine. Still not the 18-18.5 I'd expect from my Intense PCM like I usually get. So we hang out at his place for awhile and then I head home. I give it some gas going about 15mph and she takes off like a bat outta hell with 18.5 degrees of timing and 0.0KR. I'm like "Sweet! Maybe some fluke." But I got on it again at the next turn and again I had only 14.5 timing. ARG WTF!

Then I noticed some high KR whenever I slammed the gas which obviously brought the timing down...but the whole aspect of having craptastic timing and NO KR really bugs me! What on earth is going wrong here?!

The only other thing that can pull timing is torque managment if your not geting any kr.
Can you scan for convertor slippage?

Consider checking the connections at the pcm. When I was looking up my QDM in the FSM it suggested double checking all the pcm connections....

K, I'll look over the PCM but its gotta be near impossible for those connectors to come loose considering they are screwed in. :?:

WTF is up with my freakin' car! Drove to town and on the way back I went WOT 3 times and was getting my usual 17.0 - 18.5 timing. :?:

It'* like the car fixed itself or was just a lazy punk last night.
Either way I still get initial KR when I first floor it due to the trans shifting and the crazy movement of the engine and what not, but thats another issue. So why was my timing absolute crap before?

As an FYI the Autotap was setup to check TCC Slip Speed (In RPMs) and TCC Time Engaged (or something like that). At WOT the Slip Speed was always 1rpm from what I saw and when coasting it was 32rpm. Light acceleration it was 1 - 4rpms....no idea what this all means. The TCC Time was kinda all over the place. Anywhere from 0.05 sec to 3.95 sec depending on how I was driving. Again, I have no idea how to understand these numbers. :?

Sure the aftermarket PCM isn't causing some problems? How many 98 model type SSEi'* have this chip, which one in line were you?

Did any other variables change rapidly when you had the seriously retarded timing? The PCM won't retard timing for no apparent reason. It has to think something changed, or required it'* assistance.

No codes, but I still have a lean condition.

Long term trims don't go below 5.0 for the most part. At this moment I believe it to be a vacuum leak. Other than that nothing beeped, buzzed, flashed, or farted as this happened 2 nights ago.

False KR would still show up on the Autotap correct?

My initial thought is false KR from somewhere that is having the car pull tons of timing (or hit a torque mgmt setting) and then its slow giving it back. The PCM code will not just change on its own and you have had it for a while. I would try to think what things have changed right before you started seeing this symptom. Did you try a dif brand of gas?
