The last time my car stalled all of the lights on the dash came on like normal, except for the check engine light, it lit up a few seconds after the rest of the lights came on, does this mean i have a code stored in my ecu? Also, it's now light in day in difference from when my car is cold, to warm. Cold it seems to rev very high, 1-1.5, but once it gets warm it stalls almost every time i let off the throttle. Does this sound more like the maf, or a crack in a hose somewhere that only leaks once the engine warms up? Finally, I went to subaruparts.com and maf was $304, suffice to say i need to find a cheaper one
