Question about 1991 Nissan 300ZX
I have a 1991 300zx 5spd non-turbo. The issue that I'm having is similiar. I have changed out the #1 coil pack and changed out all spark plugs. It ran better for about a month, then went back to idling rough. I switched around the coil pack and still same results. I'm thinking that the its an injector issue seeing how changing the coils didn't make a differnce??? If anyone can help me here, I sure could use it. It only has 77,000 miles and its beautiful car, but I can't keep putting money into it. Its going to make me go broke!! Thanks
Get a pair of pointy nose pliers start the car let the engine revs settle, when they have pinch off the return line from the fuel rail and see if the revs come up if so you have a injector problem and get the m cleaned (don't pinch off the hose to long as it will make a fuel leak only do it for a couple of seconds)
