I'm actually having problenms with my Suv, Every time i start it the idling seems fine but as soon as it warms up it stars to misfire and i get intermitent idling. We have checked computer with electronic diagnostic devise but the cumputer is not sending out any coding so we can find the exact problem. Its getting worse every day and I'm afraid it could damage other parts. Could anyone help me please!

have you ever found out what the problem was? I have exactly same issue, i do have an engine(lean condition).......
