Engine help diagnose possible trouble

help diagnose possible trouble

i have a 99 v6 camry with 104k miles. its been taken care of properly and has had the usual maintenance.

about 4 months ago my car would occasionally shudder when switching into drive from park, neutral, or reverse. it would kind of feel like doing a neutral drop at very low rpms. i changed the tranny fluid which didnt do anything.

3 months ago by check engine light goes on. the car is still running fine. it went out after driving it about 5 or 6 times.

now fast forward to recent times. it will still shudder about the same as it has been doing. now sometimes when i am stopped, either in park or with my foot on the brake, the rpms will jump up to 1,000 then immediately drop down to about 800 where it usually idles. it will do this maybe every 5-10 seconds until i start to drive. i have never noticed this before so i dont know if it is normal or not. lately when driving my tranny seems to take long to shift. when i accelerate from a stoplight it will usually shift at about 2800 rpms when i get to 40-45. now instead it wont shift until i get past 3k.

this morning my check engine light came on again.

my driving habits have stayed the same so i dont know what is going on.

i had a camry and mine did the same thing since i got it so i always thought it was normal for that car... sorry i dont know what is wrong?!

was yours a v6 too?

could you explain that a little better? what is engine flair and how can i tell if the tranny is slipping?

have you try to see if the engine flairs when you power brake. What it sound like it doing a limp home mode. Prolly its the throttle. first check if you have engine flair by putting in drive and doing a power brake. It will show if your tranny is slipping.
