GabeRoc Posted July 15, 2005 Share Posted July 15, 2005 the spitting and sputtering is not something i can help with until more information about the current state of the motor is known. the Fuel Presure Regulator is a metal barrel with a vacume line connected too it located amid the fuel rail assembly. --gabe Quote Link to comment Share on other sites More sharing options...
BrandonsZ Posted July 15, 2005 Share Posted July 15, 2005 Igniter. Expect to replace it several times in the car's lifetime on the 280zx, it's in a bad spot get's too hot or something. Check and/or replace. Quote Link to comment Share on other sites More sharing options...
PeterZ Posted July 15, 2005 Share Posted July 15, 2005 I agree with the above two comments. There are many things that can cause your woes. Still I have to throw my two cents in. Popping through the intake may be due to a too-lean air/fuel ratio but that shouldn't make it suddenly die. While you're checking things (basics first!) you might want to check the resistance of the temp sensor. It is an NTC sensor meaning that the resistance goes down when the temp goes up. Rough numbers: 3,000 ohms cold and 300 ohms hot. Adusting the AFM for better driveability is easy but you have to be sure everything else is good. Have fun.

VinhZXT Posted July 19, 2005 Share Posted July 19, 2005 I suggest you to replace the distributor first. Both problems could be cause by a bad distributor. I've seen the poping thru the intake happened to my friend's 78 280Z. it turned out to be a bad distributor cap. Good luck Quote Link to comment Share on other sites More sharing options...
