Re: problem with cold engine

Maybe temperature sensor broken? Do you get high fuel consumption?

Re: problem with cold engine

My car also take a bit to really get going in the morning.

Under 1000rpm, no car has much power especially if cold - try and keep it above 2000rmp or higher when driving.

How bad is it really?

Re: problem with cold engine

Most likely cause is a faulty temperature coolant sensor as already mentioned. This is screwed into the top of the thermostat housing which is mounted on the right hand side of the cylinder head.
