All Idea's now needed....

Heat is now working in the car and can bled the water system very easly.

Car still runs for 5 or so minutes then dies when you restart if you let the revs die below 1000 rpm the car will cut out. Put a bit of paper in the throtle and will idle at 1015 rpm all day long.

Have so far replaced

Spark Plugs
HT Leads
Air Filter
Oil Filter
Coils
Throtle body with censors replaced

any ideas please

Also what dose the plastic manifold at the rear over the engine under the throtlebody do???
