So after successfully transplanting the h23 motor in frankenstein I managed to finally after a week get it started. Now when I start the car the rpm surges from 650 to 6,000 rpm over and over. It's almost as if the tps is bad. I've checked the following:
Briefly checked for vacuum leaks, although I would think it would have to be substancial for it to surge that much
Map voltage seems good
Tps voltage is good
Throttle cable works fine
Throttle plate isn't stuck
Fitv and iatv both have coolant running through them
Only code is o2 sensor
I deleted the Evap system because where I'm moving there are no emissions and I didn't have all the pieces to complete the system anyway so I decided to leave it out.
Any thoughts?
