my 2 cents...<P>As for my "ping" issues, I do/did have some. I have noticed with my 4Runner that the more driving on the highway that I do the less trouble I have with the dreaded "ping". I have even less instances of "pinging" after towing the boat. <BR>So I've noticed that the ping happens less when the ECU has made some slight adjustments due to driving conditions or even habits. fyi, I always leave my ECT on and when not on the freeway I turn my OD off.<P>I get my DSL @ Home on Monday finally after an 8 month wait So you'll see me around a bit more.<P>------------------<BR><A HREF="http://members.home.net/mjkapash/" TARGET=_blank>My 1999 Toyota 4Runner "TRD Highlander SX" Web Site</A>
