Default Shifting/ power issues

The other day i was driving on the highway probably 75ish mph.... i went to pass some one so i downshifted from 6th to 5th for just a little bit extra power. When i got it into gear and pressed the gas the car did nothing. No rpm difference though. They didnít rise or drop, but the car did absolutely nothing. So i shifted back into 6th and hit the gas and it did nothing. Same as when i had down shifted, no change (rise or fall in rpms) but also didnít go. I put it in neutral for a few seconds, put it back in 6th and it went again. I feel like i canít really get on it hard anymore. Then a few days later i was in 3rd and went to gas it and i think it hit like maybe 4500/5k rpms and then it acted like it was red lining..... i have no clue wtf is going on. Any advice or point me to another thread please and thank you!!!!

get it scanned, sounds like limp mode due to camshaft position sensors. (Doesn't always throw codes.)

I am experiencing the same symptoms as described by the OP. It typically happens after an aggressive/missed downshift on the highway to try and pass someone. The only way to resolve the mode that I've found - and get back to normal engine response - is to cruise along and maintain speed for 10s or so. After that, things seem to be OK. Also, the SLIP light is lit when I try to accelerate when it's mis-behaving (though the road isn't slippery, and I'm traveling over 55mph, typically).

I have 125k miles on mine, and I have no reason to suspect that the cam sensors had been replaced before. Thanks for the tips!
