Cold start

20

Asked by Nov 09, 2016 at 06:13 PM about the 2003 Subaru Forester

Question type: Maintenance & Repair

I have an '03 Subaru with the 2.5 lately it's been
having trouble starting when its cold outside. It
pops sputters stalls and runs rough for about 30
seconds then runs fine. I replaced the plugs wires
coil and fuel filter. Also compression tested all
cylinders and pressure tested the fuel system and
cooling system everything checks out perfect. It
reads codes for misfire on cylinders 1 2 and 4.
When I spray starting fluid in the intake it fired right
up no problem. Also starts fine when it's warm. Any
thoughts? Could it be MAP sensor? Or cold start
valve?
