Hello everyone! So I've been chasing down an issue in which my acceleration is getting bogged down. Basically when I accelerate about 40-80% throttle, it will cut power anywhere between 2k-5k rpm in any gear. It's not always consistent (sometime it's 2nd gear at 3500 or 3rd at 4500). I do not have a CEL or any pending codes. I have replaced my throttle body, my fuel pump, my spark plugs and ignition coils and still have the issues. I have also tried unplugging my pre cat o2 sensor to see if it would change anything, but it did not. Also, running a scan tool, it seems that ignition timing is being retarded by about 10 degrees. But doesn't appear to sense any knock or trip the knock sensor. I think it may have something to do with CVVT Solenoid, but this is just a speculation based off of a little research. If anyone has any ideas of something to look/replace that I haven't thought of, please let me know! The car has about 176k miles on it, and has been very well maintained. I've had the car since it had 25k on it. Thank you guys! I hope someone may be able to shed some light!
