hdi not wanting to start

[rickye]

Hello, recently bought a xsara hdi 90 as a runabout

recently its taking a long time to start, ive had it on the computer and the only error its bringing up is to do with the throttle position sensor.

I have noticed its very slow to turn over when cold, ive tired the battery out of my 2.5td merc but it doesnt help any.

im getting another starter to see if that helps any. I was wondering what else could be causing it. When it does start it runs lumpy for a couple of minutes aswell

Cheers
