If it is missing, the Check Engine Light should be on.  What is the CEL Code?


Does the problem go away once the car is warmed up?


With a engine code, we will be able to give you better direction.

The MAF sensor might be causing the problem.

2002 outback doesn't have a MAF sensor, they're speed density.


A failed coolant temp sensor could cause this. Do the radiator fans run constantly?

How many miles/kilometers on the car.

When was the last time the timing belt was changed?

One of my first guesses here on a 2.5 SOHC would be making sure the plug wires are OEM.  Aften off brand or old OEM will be bad until the engine gets some heat into it and that causes the wires to dry out and work "better".


You can try taking a spray bottle after it's running o.k. and spraying the plug wires to see if any change.


Over here we don't have distruibutors on those engines - so I assume you mean what we call coil pack.  In my experience Diamond brand coil pack seems to be the best.
