It has been a GREAT car and its a 4 cyl. w/ 286K miles on it. The small issue I am having is at low rpms when taking off from a stop or right when it shifts it runs a little rough. I duplicated the problem at my house w/ it in park and it is running rich just off idle to about 3K rpms and not all the time. I have a black spot on the fence to prove it! lol Coolant temp sensor maybe?
