Default loss of power?

ok i just bought a 98 legacy l 2.2 - MT AWD

anyway i been driving it for about a week and no major problems - brought it into the shop to have it inspected and had two new front tires put on - alligned - trans fluid changed - oil change ect..

anyway car passed inspection with flying colors and now ever since i got the car back it seems like it lost some power... now i know what my mechanic did should of had nothing to do with this... and i only had the car so long so it might just be in my mind and not really be happening -

once it hits 3000 rpms it seems alright but anything below that the car almost bogs down to a crawl... never seems like its gonna stall or anything even in second gear it seems like it lost all low end power...

dont know if anyone has any comments? fuel filter/spark plugs/m/f?

Was the car on synth oil before and was dino used at the shop?

Also, two front tires is bad juju for an AWD system. You're supposed to do all four unless the rears are practically brand new and of the same brand & model of tire.

Might be the trans fluid? They can be picky sometimes.

Could be placebo effect, too.

the rear tires are brand new

the car as awhole drives alot smoother esp the trans - and i just bought the car so dont know what they used before that...

im starting to think its more in my mind then anything else - im gonna try some fuel injector cleaner to see if that does anything... and go from there

The 2.2 liter motor should make okay power, as far as the 2.2 can do, above 2,700 rpm. If it's bogging, then you need to burn some more clutch when you are driving, or use a lower gear.

If you HAVE to replace two tires, I would suggest putting one new one in the front left and one on the rear right. Open diffs FTW. If you have two tires that are slightly larger than the other two, putting one in front and one in the back will save your center diff. The open front and rear diffs will quite happily spin at different speeds, as long as you have two properly matched pairs. After some time, maybe a month, they should all wear down even, and it won't matter anymore.

I still wouldn't recommend running tires that aren't all the exact same treadwidth. You can wear out your front and rear diffs running different size tires for a prolonged period of time.
