I just bought a 04 wrx, 77k miles, no aftermarket mods from a third party. I've had it for 3 days, and I was installing a new sterio yesterday and noticed a few things unplugged under the steering column and plugged them back in. Next time I start my car my CE is going crazy so I went ang got them pulled and this is what I got;
p1518 - ?
p0851 - ?
p1152 - ?
p1153 - ?
P0137 O2 Sensor Circuit Range/Performance Problem - Low Input (Bank 1 Sensor 2)
P0502 Vehicle Speed Sensor Low Input
P0503 Vehicle Speed Sensor Intermittent/Erratic/High
P1518 Starter switch circuit low input
P0301 Cylinder 1 Misfire Detected
P0303 Cylinder 3 Misfire Detected
So what I want is some advice about which to take care of first and how, and if anyone knows the first 4 codes.
Thanks for your help
