Still having problems. The second dealer (I gave up on the first) has it now and just yesterday the shop foreman was test-driving it and this he got stranded because it acted up. Earlier this week he said the tank had gunk in it and thought it was algae. So the tank was dropped again and re-cleaned, but it wasn't algae. It was still paper. So they missed some the first time it was cleaned. But now since it's been cleaned again and it's acted up on the foreman they say the fuel line and filter all appear clean. They've read a whole slew of codes but I don't know which ones. So I believe now that coincidentally, I've had more than one problem all along. I keep insisting they run down that P1280 code and check out the ICP sensor/wiring, but they haven't. Maybe now they will...
