I'm still trying to solve a pinging problem that I just can't seem to figure out. I've read several posts about the octane shorting block. Some people say don't touch it, it will totally screw up your performance and economy. Others say they have not noticed any change at all, except that the pinging went away. Soooo.....Whats the real scoop here? I'm looking for feedback from those who have "actually performed" the removal of the octane shorting block and have real world experience with this. According to my Haynes manual, this is to put the ignition into a "base timing mode", which eliminates all computer control of the timing. It also states that this is only for the purpose of testing the ignition system and to see if the computer is actually controlling the timing properly. Thanks in advance for your help.
