Odd engine problem cuts out randomly


Recommended Posts

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?????
