siteunseen Posted February 16, 2017 Share #39 Posted February 16, 2017 I'm looking with a phone but it looks like the hose is missing or unplugged. I was told to plug mine when I deleted the egr and bpt valves. It has a nut on the bottom you can turn for adjustment. Try half a turn one way and drive it. If it helps keep going that way, if it makes it worse go back the other way. Google "280z bcdd adjustment" and click "images". You'll see the fsm's directions. 1 Link to comment Share on other sites More sharing options...
JSM Posted February 16, 2017 Share #40 Posted February 16, 2017 From http://xenonzcar.com/s30/files/FSM/1978 280z FSM.zip Section "EC Emission Control System". If you have any unplugged hoses, plug them up. 2 Link to comment Share on other sites More sharing options...

FunkytownZ Posted February 17, 2017 Author Share #42 Posted February 17, 2017 did get a chance to meet up with my buddy tonight who is now keeping his 67 Firebird at his house. He had this in HS and has kept it since. Two classic cars getting to know each other on a night out on the town 1 Link to comment Share on other sites More sharing options...
FunkytownZ Posted March 3, 2017 Author Share #43 Posted March 3, 2017 Finally got around to adjusting my idle speed down to something realistic.. ran around with an idle of 1000 rpm and ran great, maybe even better. No adjustment to the BCDD needed, downshifting and deceleration and shifting were great and predictable I'll try 800 rpm next.I also put in my third tank of gas recent and switched from 93 octane to 89. Happy I did, not running as rich now. Sent from my iPhone using Classic Zcar Club mobile 1 Link to comment Share on other sites More sharing options...

When your engine runs better after you wash the car. Link to comment Share on other sites More sharing options...

FunkytownZ Posted March 18, 2017 Author Share #46 Posted March 18, 2017 Took her out all day today.. met some buddies for golf then for cold beer and burgers at Fred's Texas. Next on the to-do list:Oil change and replace drain cap and o-ringFlush radiatior and replace coolantFlush transmission and replace Replace shifter pin and bushings Replace rack and pinion boots Install new shift knob (MSA is out of those nice wooden ones - anyone got one they'd sell?)Check my AC compressor functionality and install if working My 5th gear syncros are having issues at high RPM/speed, which has me worried... shifts into 5th at lower RPM and speed Sent from my iPhone using Classic Zcar Club mobile Link to comment Share on other sites More sharing options...
