Lexus IS300 2001 2jzge
I think my cars on limp mode. Revs won't go pass 2.5k, stuck at 20/30kmph.
Cleaned the MAF, in fact I replaced it recently earlier this year.
Changed out all 4 o2 sensors over a month ago.
Just changed the diff fluid, transmission fluid and power steering. It was fine after that, although I suspected it wouldn't shift to third gear, but when I went to turn it on again the second time, still the same issue.
I also hear weird grinding noises from time to time from beneath the car when driving
NO Cel, and throwing no codes either
Update: I disconnected the battery last night and reconnected it this morning. I drove it around the block and it shifts to third and fourth gear without making any sounds, but not fifth. the engine has a roaring sound and won't rev past 2500.
Parked my car and it revs up to 4k
