ToxicDepression Posted January 10, 2017 Report Share Posted January 10, 2017 when its cold than it will idle at around 1200 rpms, but when it warms up to operating temperature, it will "buggle" and almost die down to 200 and jump to about 2000 then slowly go back down to 200. BUT... whenever I step on the clutch then the idle will even out at 2100 rpms and be steady. W......T.......F....?????????? doesn't make any sense. yeah i would understand if it was in gear but its always in neutral. (yes it does happen in gear as well) any ideas Quote Link to comment

banzai510(hainz) Posted January 10, 2017 Report Share Posted January 10, 2017 I assume you ck the cable to make sure not binding and lube it up. Carb binding also? Quote Link to comment

asid99 Posted January 12, 2017 Report Share Posted January 12, 2017 1984 Nissan 720 4X4 manual transmission with Hitachi carb, Z24 engine Is it slowly bogging out, or is it like turning off? If its bogging I would replace the jets and check the float. If it is turning off, I could do a cap and rotor replacement...if that doesn't work, I would change lead wires and plugs......and if that fails again, pray. Quote Link to comment
asid99 Posted January 12, 2017 Report Share Posted January 12, 2017 1984 Nissan 720 4X4 manual transmission with Hitachi carb, Z24 engine before you try any of those though, check the bottom cover to the steering wheel. It can come loose over time and pull on your ignition wires. Quote Link to comment

Im just trying to figure out why my clutch has a role in changing the rpms while in neutral. Quote Link to comment
datzenmike Posted January 20, 2017 Report Share Posted January 20, 2017 The clutch is part of the emissions system. Quote Link to comment

I was having the same problem and it turned out to be my hydrolic cable and slave. Quote Link to comment
