My car Mileage is 150,000. Automatic transmission.
Suddenly at lower gear, the acceleration became really slow and when I hit the acceleration padel, there is a rattling noise. I went to 1 mechanic shop and they told me the issue is with the timing chain .
I went to another mechanic shop, they also recognized the timing chain issue from code, then decided to change the timing valve solenoid, spark plug, and transmission fluid . This improved the acceleration a little bit but the problem did not go away.
They concluded that I have either a transmission problem or a computer software problem and recommended to change any of these two.
The OBD meter also showed P1009 code (Something with PCM sensor)
Please advise if anyone has any ideas.
