ISSUE
A spark knock or pre-ignition condition may exist on some vehicles with an automatic or manual transmission during steady cruise driving or under light acceleration.
ACTION
Reprogram the Powertrain Control Module (PCM). The revised calibration will reduce the potential for spark knock. Refer to the following Service Procedure for details.
NOTE: SOME LIGHT DETONATION ON TIP-IN IS NORMAL AND CONSIDERED CHARACTERISTIC
---ok read the above, light detonation on tip-in is normal and characteristic?! Detonation destroys pistons and the engine in general, how is this programmed in as being normal?!---
Just thought I would post this TSB I found on AllData and vent. Cheers
