i thought it was a bad catitlic converter so i got new one installed and it actually got worse i can keep car running in park if i keep it around 1000rpm but will noy ideal
By now there is likely a check engine light on or it was on right? You need to access the fault codes stored in the computer memory to assist in diagnosing this problem. Separately, there is a possibility of a bad MAP sensor. I see multiple confirmed fixes for stalling and the fix was the MAP sensor. Follow the codes first.
