280Zed Posted October 19, 2014 Share Posted October 19, 2014 Hi im new to this forum but just the other day I got my first 280z. When I bought the car I knew it would be a project but I thought mechanically there was nothing wrong the previous owner swapped a new l28e and a new 5speed with 50k on both. With that being said I was doing a speed run the other day and after taking my z to 100 the power curve seemed shaky like after 80mph I would get bursts of highter power and then a lull of power. Now the problem hasgotten much worse, when I get upto 4000rpm it feels like the car is fuel cutting and randomly while I drive I just get what feels like complete fuel starvation. I think it might be either the afm or the tps but I was wonderin if anybody else has had this problem. There are new wires and plugs, new fuel filter, and injectors, and from what I can tell decent fuel pressure. I also started the car and it seemed like one of the cylenders want firing... maybe somethin to do with ignition timing? -thanks Quote Link to comment Share on other sites More sharing options...
NewZed Posted October 19, 2014 Share Posted October 19, 2014 Learn how the engine management works. Take some measurements. There is no easy path back to 100 mph speed runs. http://www.nicoclub.com/FSM/280z/ Quote Link to comment Share on other sites More sharing options...
