This is so crazy man...I'm 6 months and $4k into mine and still no resolution to 4580 issue. Same symptoms really, usually low no lower power mode on the highway or cruising but as soon as I come off an exit ramp and come to a stop, bam there it is almost every time. Makes me think its some sort of low pressure issue. I had the shop its been at for the past 4 months, who found that bulletin regarding fuel return lines, replace the 3 fuel return lines, but still didn't fix it. At this point I'm at a loss, I've got one more shop to try locally but of course they can't even get me in until October 13th. I'm totally out of money and motivation to keep at this but I have a loan on the car so I have to fix it even if I'm going to try to sell it. Unbelievable. Any progress?
