High Idle P0120 P0340

[epreski7]

Long story short I bent valves on one head so I threw on another. Before this it ran fine idled at around 900 only obd code was the downstream O2 sensor. Now after I have put on the new head it idles at 2000 and its throwing a TPS, Cam Position Sensor, Upstream O2 sensor, and the downstream O2 sensor. I need help I don't know what's going on finding it hard to believe that all these sensors just magically went bad while sitting for a week. Checked for vacuum leaks and anything unplugged couldn't find anything. any suggestions would be appreciated

What kind of head did you put on the car, what kind of cam sensor does it have.

was originally 4g64 sohc, went to 4g63 dohc, and now back to 4g64 sohc head, it has the 97-99 cam sensor.

That one is over my head, first thing I have to ask though is did you swap it back to the 4g64 ecu?

i have no idea either, I disconnected the battery for 30 min while I soldered the cam sensor instead of using connectors and the idle dropped back down to normal now, there was like twice when it got back up to 2k though. Havent been able to see what codes are still on it though. No I used the same ecu for both heads only thing 4g63 has is knock sensor and different A/F ratios but no turbo on mine so I didn't swap it over
