It's in my 2000 model ranger...I've never owned anything w/ less than 5 liters....and well...this thing is such a dog its not even funny...I have to be careful getting on the interstate...so far it's completely stock. What all can be done veeeery cheaply to pep it up a little bit. I plan on a gear change sometime in the near future. I really don't want to spend 100 or more on a CAI....Only for sure thing I'm gonna do is take the cat off of it next week....if the check engine light comes on b/c of that how do I need to correct it? Any other good ideas?
