240zBoy Posted August 17, 2011 Share Posted August 17, 2011 IMO I would check timing if it is only under load. Quote Link to comment Share on other sites More sharing options...
rags Posted August 17, 2011 Share Posted August 17, 2011 I'd start with fuel. Change the fuel filter and clean out the screen in the fuel pump. Joe Quote Link to comment Share on other sites More sharing options...

JSM Posted August 18, 2011 Share Posted August 18, 2011 Go to the Xenon site and download the free FSM. I would also start with fuel first. Also check your fuel pressure. Quote Link to comment Share on other sites More sharing options...
NewZed Posted August 18, 2011 Share Posted August 18, 2011 what should the timing be set at and how do i check it??? "how do i check it" is a worrisome phrase. The 280Z is actually a good car to learn on since it is very basic and everything is accessible and easy to see. But if you don't know how to check timing you should probably pick up a book about general auto repair and maintenance, along with downloading the FSM. You'll need a timing light to check timing and a fuel pressure gauge to check fuel pressure. Quote Link to comment Share on other sites More sharing options...

Leon Posted August 18, 2011 Share Posted August 18, 2011 The procedure to check timing is the same whether it's a Datsun, Volkswagen, Ford or Volga. Newzed makes a great point: buy a general automotive repair book and self-educate. Quote Link to comment Share on other sites More sharing options...

k204drek Posted August 18, 2011 Author Share Posted August 18, 2011 (edited) well i believe i might have found the problem atleast i thought so i put the missing rocker arm back on and it runs good it has a low power but it runs the best it ever has now there is another problem well 2 actually there is a huge air sound coming from the front of the car when i rev and it it bogs out and the fuel pump is running all the time and it sounds like its straining when i rev it in park it sputters and back fires until gets to about 2500 rpms and it runs good Edited August 19, 2011 by k204drek Quote Link to comment Share on other sites More sharing options...
