Hi I would like to ask you, I changed the lexus gs430 year 2005, the head gasket, I was also taking out the motor, after installation, I can not start the engine only start | to 3 seconds and turns off when you hold the gas pedal when starting the engine and nastaruje but it intermittently as a bad valve timing, but everything I checked about 5X the timing belt is on the marks, and sprockets on the camshafts are one dot, no fault diagnostics, please help

 

Check the air flow meter connector and all fluids. Ask a mod to move your thread to the correct section, to get it more views. Good luck.
