1) Just replaced my o2 sensor a month ago OE Bosch. Everything was fine. Now in the past few days I have a weak startup, and terrible throttle response at times. Plugs and wires are fairly new. New (cheapo) fuel filter. I check the fault code and it gave me a 1221 (o2 code.) Can my sensor really go bad like that? Any other suguestions.
2) 2nd gear is terrible when I downshift into it from 3rd at speeds greater than 30mph (bad clutch or tranny). Also rarely I get a grind in 1st when i take off. What do you think?
