Have had this problem for 6 months. Computer has been replaced 3 times. Issue is when the outside temp is below 51 degrees, it craps out at 2500RPM and chk eng lite is on. After 15 minuets or so and engine warms up it runs fine. Chk engine light remains on, but goes out later in day. When above 51 or more it starts fine no light and runs great. Help. any ideas. Is there a setting in new computer that needs to be tweeked?
