Knock Retard ???????
If you had the newer style 02's cnaces are tnhey wouldnt be showing 4° KR. The Reason Mopar asked is maybe in the case you do.. that your Lt's may be hitting something like the K-member or other parts of the car causing "knock".

I don't believe changing the knock sensor it'self (which is just a piezo electric vibe transducer) is going to change anything as the PCM sets the sensitivity, amplitude per knock volt sensed, the frequency detected, etc. The 98's sensitivity settings in the PCM are more aggressive as compared to say a 2002 profile. The 2002 has more tables also that the 98 doesn't support. Are you totally sure about fueling? Not just WOT but has somebody done your VE tables yet. Just prior to WOT if you go lean then you could be getting a spike and the 98 sensitivity and longer recovery times are not helping you. I would think your problem is a combination of fueling, and the sensitivity settings, OR exhaust banging. Don't forget KISS.

What table do you use to de-sensitize knock??? I wasn't aware you could do this?? I thought it was either on or off.
