Bought the Sportage used a couple weeks ago and it has a few issues. The Sportage was really hard to start when the engine was cold so I performed a badly needed tuneup and it started great when cold. Now it is hard to start when the engine is warm. I don't know were to start looking. I don't know what the computer is looking for when starting warm. Is the computer looking at different parameters when it's warm compared to a cold start? Any direction would be great....
