Keep an eye on the glow plug light. First dont start the car before it goes out. Second it will stay on for 1 second if the coolant is above 5C and 30 seconds if below that. If it runs smooth when the light stays on its running pretty normal

Sometimes glowing twice can help.

When ther light goes out so do the glow plugs. 4jb1 doesnt have a very efficient cold start system not that it needs it
