I bought my wrx a few months ago, and I went to clean the air filter and I noticed the previouse owners cut a hole in the top of the filter. NO FILTRATION WHATSOEVER!!! So I replaced the filter, then my check engine light came on and the car ran like pooh! So I unplugged the MAF sensor and it ran great, better than it has ever ran! So I cleaned the MAF with some multi-purpose auto parts cleaner. plugged it in and still the same problem. (I was wondering if I needed to reset my ECU?) I dont have money for a new MAF $130 and I am going home for new years its a 750 mile car ride. Would it be OK to make the drive with the MAF unplugged?
ANY SUGGESTIONS WILL HELP
