Hello everyone. Not a huge issue here but just looking for some opinions. When my car is warmed up and idleing it cuts power to the fuel pump randomly and speratically. Occationally causing it to stall. It is only for a split second however sometimes it happens a few times in a row. If i rev it up by even 100 rpms it seems to go away. Im thinking either circuit board problems, bad settings, or bad connections

I have recently rebuilt the VG30E that is in my 1985 300zx, NA and automatic. It was a stock rebuild with a rebuild kit except for the cams, which were replaced by a Wolf Technologies AZ314-000S1. Because of the new cams I also opted for a 1987 ECCS with JECS#: A18-679 M83 with nistune installed. The engine has been assembled for a couple weeks now and it's still having problems. It will fire and it seems like the timing isn't set right. We have gotten it to run long enough to hopefully break in the cams, but it has rpm fluctuations under throttle and wont idle. The current th

Hey guys, I'm having idle issues where I can't keep the car running and it never seems to want to catch. Either it runs too rich and dies or runs too lean and runs very badly. I have to keep steady pressure on the throttle to keep it from dying. Clearly that means that I need more air, so I would lower my VE values and it wouldn't seem to help any. The car ran better and would actually idle around 600rpm with all the idle valves on the plenum, but none of them were wired up. I've since took them all out, as well as the egr valve, and blocked all the holes off. I have my tune and a few datalogs

Hey guys, I got something out of the blue and hoping a random angel-sent individual will have some sort of assistance for me. I recently installed triple Dellorto dhla 40's on my engine via an SK manifold. The engine specs as follows: stock l28 bottom end with the exception of flat top pistons. The head is a rebuilt N42 head with a mild Rebello cam. The carbs have 38mm choke, 132 mains, 33 pump jets, 7772.8 emulsion tube, 210 air correctors, and 58 Idle jets. I should note that the engine ran with SU's (SU's were replaced with triples due to leaking throttle shaft) Replaced parts: plug w

Doing a slow restore on a 72 240 i picked up. Weber 45s were having some trouble sneezing and leaking so took them off to clean em up and replace gaskets, set floats etc. Noticed these adjustment screws which i find no mention of in Haynes manual, or any online reference ive found. These are the later 152s with nitrophyl/spansil floats so im thinking it was a modification on later models? has a white plastic hat/cover. one on each throat. with plastic cover removed needle screw with fastener nut needle pokes through main venturu/choke into carb throat (uppe

Hi everyone, I've had an issue with my Z for a while which hasn't really been a big deal but I figured I should probably figure out what it is in case it does turn into an issue that could be prevented. Every so often when I start my car, it idles rough (usually between 500-700rpm), shudders, and bogs down. It loses quite a bit of power until I drive it for a bit. After that, it's fine. It's happened with the engine hot and cold. Part of me wants to say that it seems to be the symptoms of the cold start injector firing when it doesn't need to, but I'm not sure. Any advice is
