So my 2000 LS400 started misfiring recently and it can go a week running fine and then all of a sudden it will misfire at every stop light. Car seems to run fine when going but whenever I hit a stop light it will usually start shaking pretty badly, then sometimes it will be still. Have got the code for random misfires and the cylinders 1,3,5,7. Along with p1346 p1349 with the VVT. I have replaced the spark plugs, the car ran fine for around a week then started misfiring again. just changed out the oil control valves and still is rough idle and shaking but very slightly. The car idles super low too when still. Along with a super strong smell of gas when starting the car and having it warm up too.
