jersey280 Posted March 15, 2016 Share Posted March 15, 2016 Finally got her started! 1976 280z with 6-1 MSA headers and MSA performance exhaust. It revs fine and all just sounds a little off. What do yall think? https://youtu.be/bvOdFOTn6al Quote Link to comment Share on other sites More sharing options...

NewZed Posted March 15, 2016 Share Posted March 15, 2016 just sounds a little off. What do yall think? Idle speed is low. Not good for oil pressure or alternator charging. Beyond that you'll need to define what you mean by "off". Quote Link to comment Share on other sites More sharing options...
jersey280 Posted March 15, 2016 Author Share Posted March 15, 2016 I haven't owned a 280z before so I am unaware of the "running right" sound to look for. It sounds a little lopey and was concerned it may be a vacuum or afm issue. I am attempting to see if one of you gurus would be able to tell me if besides increasing the idle speed, do these cars naturally have a lope to them? Engine is a recent rebuilt by a PO and I've spent countless hours cleaning, checking voltages and assuring things were connected correctly, which they all appear to be.

NewZed Posted March 15, 2016 Share Posted March 15, 2016 Mine sounded "cammy" when it was running rich. My neighbor thought it had a performance cam. It doesn't. Raise the idle speed, to at least spec., let it warm up and see what you think. You're off=spec. right now (low idle speed). so it's going to sound off. All engines sound about like that when the idle is too low. You've checked a lot of stuff, might as well change the idle speed to where it's supposed to be.

jersey280 Posted March 16, 2016 Author Share Posted March 16, 2016 Thanks as usual Zed. Just adjust the idle screw? Or adjust and advance timing? She's sitting at 550-600 at the moment. Quote Link to comment Share on other sites More sharing options...
