QuestionI am sorry Mr. Von Sudderth,
but I did not ask this question before (quite for several years I did not visited this site). I would greatly appreciate sending to me a copy, if it exists. Thanks! Rick -------------------------

Question -
My Nissan Altima93(VIN#1N4BU31FOPC1161190) is acting up. The idle RPM is fluctuating and when I come to a stop stalls. I changed the distributor, injectors, spark plugs, etc. The mechanic changed the idle RPM to 1200! Now it does not stall as often but it is not right!
I tried to read the ECU. In on-board diagnostic test mode I, the RED LED is ON, and in test mode II the code is 45. If my car is a California model, it seems that it has a leaking injector.
If it is not a California model, the RED LED (ON in test mode I) shows that the ECU is bad. How can I tell if here in Spring, Texas I got a California model or not(see VIN#)? Any solutions to my problem?

AnswerRick,
I am sorry but I thought the answer went through yesterday before the system went down. Anyway, the problem you have having is probably due to the power valve in the carburetor. The thing looks like a brass pallpoint pen with a couple of wires coming out of it and it is in the carburetor. You have to take the top of the carburetor off to get access to it and when it is replaced you should be able to cut the idle down to normal. On the part of it being a California or Federal car is easy to check the door sticker on the drivers side. It should state that it is a California car. If not you can call the local Nissan parts counter and give them the vin and they can look it up. I would not change the ECM until you replace the power valve and disconnect the battery for five minutes to see if the problem goes away. This part is for the red light and not the carburetor. Once the battery is hooked back up see if the light goes out. Be sure to be gentle on that screw as you can damage the circuit board and that will cause the light to stay on.
