My car is starting rough when it sits for a while, either overnight or after a vacation where it has been sitting in the garage.
The fault code says that there is a "Fuel Trim Malfunction (Bank2). Any thoughts of what might cause this? I recently replaced the fuel filter and noticed some (small) cracks in the line connectiing the fliter.
Thanks for any guidance that you might be able to give me to rectify this issue.
