Yeah sorry guys, should have told you that we did replace the accelerator pedal when we 1st had the trouble come up......cost about $500AU and we thought this had cured the problem....but nooooo. So, reading all that you have found using the cds, me thinks that maybe the wiring should be replaced completely, and not "destressed" which is what the shop admitted they did instead of replacing like I asked them to.
Whaddya think? Jan O
