Removed my aftermarket intake Cone Filter which goes into the Air Flow Meter (L28 EFI) and found it to be very dirty looked into the pipe it attaches too and feeds into the AFM and theres dust in there.. Car's running ok, but should i try and clean the AFM, since dirt must have gone in there... Whats the best way to do this? Thanks..

Hi I have 2 questions, 1. I'm doing an l28 f/i build on my 72. For dress up purposes, do i really need to have the injector cooler? At least i think thats what it is. It's the thing that looks like a turbo on the passenger side of then engine that blows air up and over the valve cover onto the intake manifold. I think it looks really ugly and i want to take it out. 2. I notice that most of the carb. engines have those valve cover breathers. Can they be used on the f/i engines as well? ...or does a hose need to be routed to the intake track. Right now i have one routed to the throttle body. Is this a good or bad idea. Any suggestions would be appreciated.

My sons 81, 280 wouldn't start so I shorted across the relay and it started. It immediatly began running extreamly rich, missing wouldn,t rev beyond 3,000. The car didn't make it 1 mile before dying. I at first suspected the fuel pressure regulator and changed it. No luck. I then in the assumption that I damaged the computer changed it same result no luck still rich. The O2 sensor is fouled but seems ok and is not shorted out to ground. I am out of Ideas and do not want to just throw parts at it PLEASE HELP!!

At the risk of upsetting everyone, especially the adinistrators, I want to ask for your advice on behalf of a French Z owner who has a 1980 1.8l injection Silvia as well. His fuel consumption has gone up and the amount of CO has risen from 2 to 4. The motor runs cool (oil at 70 degrees instead of 110 and he therefore thinks that the injection unti believes the engine is always running from cold and gives the engine more fuel just as if the choke/starter is engaged. He has tried fitting an adjustable thermostat which has helped a bit but still the engine needs some insitance before starting. Before the engine fired up first time! There seems to be a loss of power on the ro…

Has anyone gone to town with EFI on an L28 in a 240Z?? i.e, a custom programmable ECU system, bigger injectors, aftermarket injection throttle bodies on a Weber type manifold etc.. What have you done and are you happy with the results??

Hi all, I sold my '75 280z, but, I'm keeping the engine (totally blown) and EFI. I'm thinking about using it as a possible solution for my '71 240z project. But, I really don't know what I should remove. Anyone have experience moving EFI from one car to another?

I posted something about this about a month ago but the problem didnt go away. I have a 77 l28 fuel injected in my 240z. After cleaning up the fuel rail/injectors and also the throttle body my engine developed a idle problem. When you push on the gas the rpms go high and never come back down. The linkage and everything is ok. The only way to get the rmps to come back down is if you put it into gear or to shut off the engine and turn it back on. (but once you hit the gas again...it comes back) I found that if i move the wires around and rotate the throttle valve switch the idle changes. I havnt been able to find any vacuum leaks...So can i conclude that the throttle body i…
