So I just recently bought a 90 300zx tt 2+0, she had been running great all summer until a couple of days ago it feels like I went from 300 horses to about 100... She fires up right away but idle is a bit shaky. I checked for codes and got code 13 (engine coolant temperature sensor) and nothing more. The problem is when I accelerate, it feels like the fuel is cutting off, shaky, jumpy acceleration throughout the rpm range and she feels like a snail!! Could this be a fuel issue? I just put new oem spark plugs so I don't think that's it...Any suggestions or help would be greatly appreciated. Thanks
