  1. Fuel pre-pump questions

    Hi everyone, first post. Been using this site for years now and have saved literally 1000's of dollars. Thanks so much. 2001 Saab 9-5 2.3T with 225k miles, pretty certain the engine was replaced at 120k (that's what the previous owner told me). The car was given to me for free, so was pretty...

    9-3 Sedan, Cabrio '04+, Combi, 9-3X Workshop
    So about a month ago, I noticed my car didn't have as much power as it had when I bought it. It seemed kind of sluggish, and seemed to hesitate and surge a bit, but I thought nothing of it at the time since it's very cold out. After a while it got worse... and worse... and even more...
