Dponce Posted July 24, 2012 Share Posted July 24, 2012 So my 280z is having this weird issue where when its cold itll run good have power. However soemtimes if i start driving it feels like the car hits a brick wall when i get to about 3k rpm(not sure of exact rpm because my rpm gauge does whatever it wants). But itll usually power past that and ill be good to go. then when it hits operating temp the car will have that loss of power feeling again and eventually it will just stop putting out power and backfire like crazy then die. But if i wait 5 minutes itll fire right back up and drive as if nothing is wrong. Im just curious if anyone has had this problem before and what their fix was. Sorry for the improper grammar, etc. Quote Link to comment Share on other sites More sharing options...
Dponce Posted July 24, 2012 Author Share Posted July 24, 2012 Oops forgot to add that she does run a little rough when she gets to operating temp. Quote Link to comment Share on other sites More sharing options...
OldAndyAndTheSea Posted July 24, 2012 Share Posted July 24, 2012 Just throwing it out there. But maybe your fuel is getting too hot. Do you have any heat shield or insulation for the fuel rail? Quote Link to comment Share on other sites More sharing options...
