    sluggish in the cold weather

    hey, Ive been a bit confused with my wrx (06 w/ 35k). The weather where I live has been changing lately and it has been raining and getting colder, and my problem is that my car has been real sluggish. My car seems to be reving up more than usual, but I'm not going faster. My best guess was that it's running lean, and if so could it be a computer problem. Btw, it feels like this even after a good warm up. If anyone has an idea I would appreciate it, thanks

    if anything- my car always performs better in the cold (aka 50-60 degrees here in good ol' florida) so thats odd.

    are you stock? if not what mods do you have?

    my car is stock, and it was running well in the 60 degree I had about a week ago. But since it has been below 50 my car has been acting like I described

    ~50 degree temps = great performance here. The power specs in my sig were taken with temps in the low to mid 50's.

    Well, alright, I would appreciate some suggestions then or something because I'm sure the dealer would tell me it's fine.

    it's not my clutch or tire spin it just seems like I'm missing 40 hp or something. But is it possible that my CPU might be trying to feed the same amount of gas to my engine while the o2 molecules are more dense, causing me to run lean?

    Does your car feel like it is running out of gas at higher RPM?

    Do you track your gas millage? If so is it not as good this tank?

    Above 3k rpm the ECU starts pulling information from the O2 Sensors. Maybe one of them has gone bad and is feeding the wrong information to the ECU.

    Is your car still under warranty? If so take it back to the dealer and have them check it out.

    that's a good idea, I've got 700 miles of warantee left so I sound check that.
