I have a 1990 Mitsubishi mirage. It is hard(Almost impossible) to start when temps are below 40 Degrees. When it starts it idles terrible(barely running) until the temp gauge starts to show the car is warming up. The warmer it gets the better it runs.
I replaced the Engine coolant temp sensor,rotor and cap and ran a scan on the engine. It gives me code 13..15..21..and 25. After replacing the Engine coolant sensor I unhooked the Negative post form the battery for a few minutes and then hooked it back up. For the first minute or more it just gave code 15 over and over and then added 13-21 and 25 again.
On your site it shows 13 is the intake temperature sensor, 15 is SC motor position Sensor, 21 is coolant temperature sensor, and 25 is barometric pressure sensor. Just wondered what I should replace next to see if I can get this car running.
If I put a heater in the engine compartment and warm it up it starts easier but still idles bad until it warms up.
