The car is going back in tomorrow night so they can do a fuel pressure check overnight. We're going alittle crazy with this problem trying to figure out if the idle and starting problems are part of the same issue or two seperate issues. Since neither is getting resolved, it feels like we're going in circles.
The car isn't sluggish at all; just the king of mis-fires in the morning. After 30 seconds or so, it settles down. While it misfiring, the car will rev just fine - just with a whole lot of shaking.
Oh great - two parts they can replace
While not excited to spend $200 per pump, I would like to see the car just completely fail one of the tests. However, I'm still not optimistic. How do the fuel sending unit, fuel pressure regulator and/or accumulator figure into the "rough start" problem?
