If the temperature drops below 20°F, I experience the first stall with the same symptoms. When I restart, the engine surges continuously between 800 and 1200 RPM, and the EML light comes on along with the yellow brake light and the 4x4 light. After about a minute of surging, I shut the engine off, wait a few seconds, restart, and everything runs fine again. Once the engine warms up even slightly, the stalling and surging never happen again, and I have no issues until the next cold morning. I sent my equipment to the pros, and they got the job done—A++++! Everything back to normal thank you guys
