1977 280z silver Posted April 26, 2010 Share Posted April 26, 2010 1977 280z I really need help with this I have no clue what the problem is. My car runs great awesome power and speed but so often when im driving it losses power drastically. It doesn't want to die (idles normal) but wont do anything I can (sometimes) hold the pedal slightly and it will keep the same speed for a while. To me is acts like its starved of fuel or it just starts to miss fire. The only things ive done to it is removed the pollution control unit and put headers on it. Ive replaced fuel filter checked fuel pressure replaced the afm did a complete tune up new wires and plugs Any opinions????? Quote Link to comment Share on other sites More sharing options...
sweetleaf Posted April 26, 2010 Share Posted April 26, 2010 What was your FP under load? Quote Link to comment Share on other sites More sharing options...
1977 280z silver Posted April 26, 2010 Author Share Posted April 26, 2010 The way i tested the fp was at idling and reving it. I didnt test it while driving though if thats what your asking? Quote Link to comment Share on other sites More sharing options...
