Engine won't accelerate when cold
Have 1993 Aerostar w/3.0L engine. All spring, summer, fall, engine runs fine. When cold weather hits. I have to let the motor warm up for 10 to 15 minutes (depending on the temp) or else the motor stalls out when accelerating. Symptoms are same as bad choke on older carburated engines. Check for codes, but are none. What could be problem?
