sorry for the late reply! I had checked that and it seemed that my tps was working fine, though I did notice at idle it likes to jump between 0% and .38% which is so little but that seems to be enough to make the cars idle jump up and down about 70 Rpm or so. That engine surging is super annoying. I'm not sure if this is typical or not so today I will replace it. On a side note I talked to my mechanic and he seems to think it could be the torque converter. To be clear he never looked at it because I couldn't leave it with him and he was booked. But from all the research Ive done it really does seem like it's the solenoids. The trans has been acting up like this all month. I ran some test on the solenoids today and everything seemed fine...took it for a drive and as if by magic it's working amazing. I didn't expect my car to be in some quantum state..... Makes my life harder.

So just listening to the engine I noticed a VERY quiet scraping in 3rd (it was either 3rd or 4th). Any ideas on any of this crazy mess?
