2019 subaru sti cylinder 1 misfire
I was wondering if anyone can help me with any ideas to diagnose my car. i have a cylinder 1 misfire and running lean. ive changed coil packs, spark plugs, injectors, compression came back good. ive checked fuel pressure that came out to 40-45 psi. the maf sensor has connection, ive checked for vacuum leaks multiple times. everything has been swapped around, the misfire stays consistent on cylinder 1. it misfires only when hot, the rpms will jump up and down at idle, and occasionally does a crank and no start. im going to be doing a leak down test shortly to see if the compression test missed anything. maybe it could be the crankshaft sensor? timing? oil control solenoid? let me know if anyone has ideas. it is completely stock as well, and has 102k miles.
