well i've been cleaning my car a bit, trying to get it running right. i don't think number 3 is getting any fuel. pull the plug and it appears to not be getting fuel. pull off the injector wire, nothin changes, pull off the plug wire, nothin changes. number 1 had the same problem, but it turned out the actual injector wire was corroded, fixed it by cleaning it. but number 3 i cleaned as well, no change. I drove it around my complex a bit and it started clearing, but once i parked and let it idle a bit, it sounded rough again.

I'll be the fuel rail is gunked up or soemthin.

it does have a bit of trouble reving if you try smashing the throttle, but give it a bit less and it'll rev up no problem.

it's a 78 280z i've been fighting the grounding gremlins all weekend haha. i finally got that sorted, but i do believe the injectors and fuel lines are crudded. I just want some opinions before i dive in and spend money where it's not needed

(it does get spark to all cylinders.)

It just so happens that there is an active thread going about this right now.

There are a couple companies mentioned that work on injectors, and Stephen has posted a photo of his injector checker...
