Hello,
Today I did my first drive after restoration and upgrading my GN. Car ran great for the first time, but made some smoke on idle. Doesn't look like burning oil. It looked like running to rich on idle and on drive. No smoke on any driving condition. Fuel pressure with disconnected vacuum line on pressure regulator is 43 lbs and with 38. When I stop the engine the fuel pressure drops down to 20 lbs after a minute. Is it okay?
Is running rich normal with a TT chip or did I anything wrong when I rebuild the engine? Maybe I havn't the right timing for the cam sensor? You can see below what upgrades I have on the engine.
Any help appreciated.
Thanks Thomas
