Got S1 rs turbo when idle its seems its running lumpy as if it was running 3 cyclinders but its not it revs in neutral but dies when i try to run it under load any one had this problem or has anyone any ideas cheers

 

Hi. Does it drive at normal acceleration or does it just cut out as soon as you try to drive?

just as soon as you try and drive it to dies

 

Check all your hoses to make sure there are no air leaks. RSTs don't like them due to mechanical fuel injection. Would prob still have problems with no load too though but check anyway.
If your fuel pump is worn would also do this. They often get quite noisy when on last legs. A garage should be able to check your fuel pressure for you or you can buy a gauge and check it yourself if confident. Fuel pressure should hold good throughout rev range but with kaput pump it will drop off causing engine to die like running out of petrol.

It could could be quite a few things to be honest though but worth looking into those two for starters.

 

I would start by checking the CO at idle, if this is wrong and very lean the rest will be, and will give the symptoms you have.
Do also check all the pipes for any loose ones as advised as you should do this anyway.
