I am going nuts here. It seems that my 1987 Nissan truck has a relatively advanced ECU on it and is now working against me when the Hydrolyzer is working. I actually got worse mileage for a while which confused me. I checked everything I could think of, and then read the codes off my computer only to discover that the 0/2 sensor error was triggered. I assume that it was reading rich and compensating by adding more fuel to the throttle body. This is what the articles on this website indicate anyway.
So, before I start messing with my truck and purchasing an EFIE for it, is there ANY OTHER sensors that I should be aware of??!! I am on the verge of calling this whole thing a bust. I am sick of jacking around with my truck so much. Purchasing a motorcycle sounds easier (AND it draws more female attention)
1987 Nissan King Cab, 4x4, truck (D21 model), 3.0L V6 engine (VG30i model).
Types of sensors from the FSM descriptions:
1) an upstream 0/2 sensor made of ceramic titania reading 0 to 1 volt.
2) It also has a hotwire style air flow meter
3) Potentiometer style throttle sensor with varying output voltage (it also doubles as a hard/soft idle switch).
4) Factory cylinder head temp sensor that uses a thermsistor to read the temp
5) a mixture heater which atomizes fuel during cold starts.
There are a few other sensors, but I dont think they directly affect the stoichiometric ratio for the fuel.
