Already done! Ihonestly think it is not a fuel issue! Will have to wait till wednesday till the dealer can have a look at it!!! Good luck with this man...Hope that you did not mess with the TPS screw...if you fiddled with it then the dealer will go through all that you have then maybe...maybe...narrow down to this. And if you did move it then, according to my service manual, it will lose a little in performance after its readjusted. This is the way I interpret the literature...check your manual and then check your memroy to see if that was an issue.
