Hello all! FNG here. Not sure this is the right forum to post this.

09 Forester standard. P0302, no other codes. (still trying to figure out "live data", and "freeze frame" stuff.
Engine, traction, cruise lights flashing.

Leak down test good I think. 90psi applied 88psi out (same across all 4 cylinders)
Compression test good I think. 175psi across the 4 cylinders.
Coolant block test good. Solution remained blue.
Swapped out MAF. Voltage and ground good at connector.

What should I check next? Vacuum leak? Fuel pressure? MAP? EGR valve?The kitchen sink?

Any tips would be appreciated.

Stu

Thank you for that quick reply. I forgot to mention that I swapped out the coil plugs and wires. I'm going to test the fuel pressure next and see whats up. Then I'll watch some videos on how to check for vacuum leaks, and continue the process of elimination. I'll post when I get it right. Thanks again!
