astra bertone yesterday a 2001 plate buy again, for an affordable price.
seems to have a rattle on cold start that lasts a couple of seconds the idle speed seems to be very low until the for.
so I decided to bring the car and trailer to cure health.
I did a test after two miles and seems to be very good.

Do you recommend chain kit?
While only tensor z20net replacement?

I hope to save this z22se ...🙂

I have panic now, I think we'd better not start the engine until the new kit is installed(n)

Rattle could be a crack in the exhaust manifold
