Bad/loose ground. Any repairs recently? Check engine light on before?

I suspected a loose ground also, but the old owner added about 3 extra grounds on the engine block to frame. It has been running fine for last three days. But the TCS off light is always on a Slip light both those never go out.

I put on code reader have a P0345 and a P0462 could the camshaft sensor put the car in safe mode??

Yes, camshaft signal is very important to everything. Codes are very important and useful, never disregard them.

I just replaced the Drivers side (curved) Bank2 Camshaft sensor, very easy to replace. reach behind engine from passenger side and take 10mm bolt out, squeeze clip and plug poped off. Replacenwith new while having the battery terminal off the whole time, reconnect cable and run's great.
Now to the gauges flashing on and off theres a white plug with a blue relay down by the battery has orange wires about 4 wires. The battery was not secured down and smashed the plug. Not every thing works great so if your speedo or tach jumps up and down or dies for no reason check this plug
