I have a ZC in a 91 CRX HF. Even before the swap, I had issues with the motor bogging down randomly. The simple way to solve the problem was to unplug the TPS and all the issues went away (minor loss of power for obvious reasons). I've replaced the TPS sensor and measured it at both the TPS itself and the ECU. At the sensor it measured exactly .5v (at close) and at the ECU it measured .15-.2v less than the sensor. I was told that the .2v loss is insignificant.
I've had to unplug my new TPS because my car behaves the same way with the new sensor as it did with the old. My only guess would blame the issue on something in the wiring. I have even used two separate ECUs to see if one was faulty (Si and Integra).
I have checked and double checked my installation of the sensor. I have measured it several times at the sensor and the ECU. The sensor reads fine and doesn't throw a code, but car isn't capable of getting the proper air/fuel ratio when its cold or when shifting into another gear.
Anyone else have something like this before? or have any ideas on what else I should check?
