Hello all and thanks for such a nice forum.

I have read most of the threads relating to this issue but just want my own with my own problems talked about.
My 1990 730 auto has starting problems.
If I use the car every day its mostly fine, but if I leave it for a few days it gets hard to start and runs very poorly when it does start.
on a day it starts fine I can run it a few miles then it will start to missfire and just not run very well.
when I reach my destination and stop the car it wont start for an hour until the engine is cold again,
then it will run poor for a few minutes and then run like it never had a problem,just very smooth like it should.
On a day where it wont start I will have to give it throttle to start it and it will missfire and backfire a bit
and wont really take revs past 1500 - 2000 unless you ease it up.then if you stop it it will not start for an hour or so or just start and run rough.

temp guage is fine. all other things are fine.

I have read about the checkvalve replacement ,does anyone know where to get one in the UK?
I have also read about a leaking injector. anyone think it might be this ?

hope to get some replys soon. its driving me .
thanks
