Hi datzenmike If you check your diagrams you'll see they are for California and Canada models only, Not Federal 1984 sentra California and Canada models had vacuum advance dizzys...Not Federal. All Federal had Electronic dizzy system called ELECTRONIC IGNITION TIMING CONTROL- No vacuum advance...Timing controlled by Computer (without a doubt)- No vacuum connection on dizzy. Federal models were the only ones equipped with the infamous hopeless chokeless carburetors and the electronic distributor - completely different carburetors and ignition systems than the california and canada models. Two different animals. Thanks

(1) OK on the carb connector, but will I need to connect each feed and return together because when disconnected power dies. (2) Not vacuum advance dizzy on the sentra - Electronic, controlled by computer. It has a four wire connector...vacuum advance does not. Thanks

Hi, I have looked through all the post, but have a few questions on the connectors. (1) What do you do with the connector that goes to the feedback carb, If you unplug it car wont run, so you just cant cap the eight wires ? (2) I know I have to go with a vacuum advance dizzy, but what to do with the four wire connector that goes to the electronic dizzy. What wires do I need to connect to the vacuum advance dizzy ? (3) Can I now completely do away with the computer ? Thanks in advance

Already have the 1984 nissan service manual, and chilton, and haynes....Seems like since they only used this system for two years...You can't get any information. Looking for someone who actually worked on them. Thanks

Need procedure to set, and adjust idle speed control actuator on 1984-85 Sentra, VCM, feedback carb system. Thanks

Which wire do you mean ? The connector right on the VCM ? Also, in your earlier post you mention a throttle valve switch ? not sure where or what that is

While I've been researching articles about the vcm feedback carb system on my 84 sentra, I came across this description and it seems to fit, it was called ( The Hopeless Chokeless System )

Float is right on the money, I'm going to test the senors and switches according to book. The IAC is actually that big -( idle speed control actuator,) with five vacuum lines running to it. I'll be checking that too... tomorrow morning, its up to 106 now. Not sure on picture, doesn't give you option to browse photos Thanks

Yea, I have the feedback, electronically controlled carburetor ... No rivets or automatic choke,It has a Idle speed control actuator and lots of sensors and switches, all controlled by the computer. The butterfly is barely opening Even when up to op temp...trying to figure out how thats controlled..which sensor sends to computer to control this? or is computer messed up? Checked all connections and plugs, vacuum lines, and wires. I found some test I can try in the manual...it also has a air-fuel ratio solenoid inside the carb that may be causing problem.

Thanks for the link, and for both of your advice. Its 109 out there right now, so I'll research your advice and try it out in the morning. Have to locate the throttle valve switch, and read up on the link. Just in case..its a hitachi DFE 2832 2barrel....Are they fairly easy to rebuild ? I'm good taking things apart and putting back together, but haven't tried a carb. Thanks

Hi, New plugs, wires, rotor, cap, o2 sensor, timing set to spec,cleaned carb, compression test great, rechecked everything twice. Fires right up, but will sometimes idle fine, then will speed up by itself, then idle way down, straighten out, then do it again, driving me crazy! Any help would be great

Hi, I can't find the procedure anywhere, to adjust, set, the idle speed control actuator on the 1984-85 sentra feedback carb. VCM system. Have the service manual and chilton, and haynes...but there is no information on it in any of them. Just a lot of post saying not to mess with it...Well its to late for that, need to find someone who has worked with these. Thanks

Thanks, Zilla, Mike and Daniel One at a time only, and to spec !!

Hi, Retorquing the head bolts on the 84 sentra 1.6 - JUST RETORQUING not installing new gasket. Should I just retorgue to the spec'd 50-54 foot lbs. or a little more. ??

Thanks for the advice. Very glad to hear you guys don't consider that a common problem with the e-series. Will be retorqueing head bolts today...one at a time. I can see already that RATSUN is a great site to have joined. Will be back with many more questions, I'm sure Thanks again mickey-d
