2001 malibu 3 problems

[ridds79]

my malibu has a mass air flow sensor code p0102, replaced sensor with a used one and still getting the same code. it is also slaming into gear when you shift out of park seems the worst when going into drive, and it is stalling sometimes seems to do it the most when the car is warm and under a half tank of gas. could all of these be caused by one problem? any ideas what might be going on?

used one may be bad if your getting same code? have you looked and seen if you can take that apart and clean screen?

autozone has it in spray it's for throttle body cleaner but it will work to clean screen.

any idea if that mass airflow could be causing the other problems? i cleaned with gm throttle body cleaner still no change. the hard clunk into drive worries me the most any ideas one person had the same problem said they changed the IAT i dont know what that is do you

clunk like it's in your tranny? check the unaversal under your hood on the sterring rod coming from sterring whell also have someone pull in gear while you look at engine see if it's raising to much like moter mount's and tranny mount.
