    Apologies for posting so many times, but I hope whomever is reading this can get some guidance out of it. So I took the car to Ricerzone and had them scan it, and 3 codes came up. p0171 p0122 p0102

    -One was for the MAF having low input (I had it unplugged just 2 days before, so that one's off the list for now)
    -Second was for the TPS (throttle positioning sensor) haven't ruled this one out yet, but being that I just had the TB off the car to clean it I suspect that unplugging it and having the eye turned to the first click triggered this code also.
    -Third, i'm not doing the codes in order, sorry. was for engine running lean in bank 1, which i sould assume is the front bank.

    After looking on here for the codes i found multiple writeups saying that the lean mixture code is due to a vaccum leak, o2 sensor, or MAF, or a combination of the 3. As mentioned before, I do have the front o2 sensor at home but can't get it installed till next week, at that time I will also check for vaccum leaks with carb cleaner and see where that takes me. Finally I will be cleaning the MAF yet again to ensure that it is still working properly. Hopefully that will fix this problem. Hope this helps someone, any more input is greatly appreciated.

    Interesting about the codes..I did replace the MAF(no change), done nothing with the sensor, and yea maybe a vacuum leak could contribute to that symptom I'll take a look at that..thanks for the info
