scan the computer again for codes. driving the car with flashing ck engine lite is damaging the valves and the cat converters. any po300,1,2,3,4,5,6,7,8 codes indicate that cyl. #misfire. most likely plugs and/or coils. if the po174 is back i would take a look at a possible vacuum leak in engine somewhere. the o2 sensor could have fixed the 153/4 but still could be more

This can be your Idle control valve, when you turn the air on it puts the engine under load and your computer will increase the idle automatically to prevent the engine from cutting out.
When you are standing still and the car is shaking, by touching the accelerator very softly does the shaking stop? If so check the idle control valve.
I hope this will help.

I just had this fixed on my suby today. The cause is that the spark plugs, go through the valve covers on the 2.5 l .When the o rings in the cover go, the result is oil in the spark plugs. The cost of the repair in Canada was about $500 including diagnostics as well as new plugs and wires About 1.5 hours labor and new seals and gaskets. It now runs like new. This is a common problem for this subaru engine as well as for the dodge neon.

Hi, this is an issue that concerns the coil pack on your engine. It is malfunctioning. and, i recommend testing to make sure of thsi issue.
Check for dirt, corrosion or damage on the terminals and repair as necessary.
Measure coil primary resistance between ignition coil pin 4 (B+) and pins 1 (coil 2), 2 (coil 3) and 3 (coil 1) .
Resistance should be 0.3-1.0 ohms. If resistance is out of specifications, replace the coil pack. If resistance is within specifications, proceed to secondary windings testing.
Coil 1-cylinders 1 and 5 Coil 3-cylinders 2 and 6 Coil 2-cylinders 3 and 4
Resistance should be 12.8-13.1 kilohms. If secondary resistance is not within specification, replace the coil pack.
You can jump this link below for a good look at a diagram of the coil pack.
