Ive noticed recently my cars been laggy, like if im slowing down it'll feel like the rpms are just hard to like.....get up
what could this be?
it shifts fine so it aint transmission
it's an auto btw
it has about 100K Miles on it. could it be idle control valve, but that wouldnt make much sense cause it's while im driving
or o2 sensor
if it's o2 sensor needs cleaning, anyone got instructions on how to clean it?
