hi guys, I have a 2015 Toyota Camry with 110k miles. The car has a zero mechanical or electrical issues. Last week I decided to do a full service by myself including:
1) changed transmission fluid (I used Toyota fluid, I added same amount of old fluid came from the car to be sure it have the same level)
2) changed sparking plugs (used toyota parts)
3)changed coolant fluid (used Toyota coolant)
4) flushed the brake fluid
I watched Scotty’s videos and others so my procedure was correct. Now the car run with out any issue, but it is started to have a rattle sound when I am parked then change the transmission from P/N to R to D mode! I can not recognize if the rattle coming from the engine or transmission. I believe the rattle will be worst on cold start.
I checked for code using BlueDrive devise and I found only code P1604 (this code was on the car since a year therefore it should not be from my recent service for changing the fluids).
I am will appreciate it if you advise me what I need to check?
Is it rattling at idle with the shifter in P?
No only when I shift to R or D (it rattle more on R)

When you changed the spark plugs, did you do them one at a time, reconnecting the correct coil pack to the correct spark plug?
Yes as I remember! How can I verify I connected the correct coils? Also my question, if I did connect the wrong coil, can the bluedrive code reader show an error code?
