as above, right when i start it up from cold it will not idle under 1100 revs but will tick over fine on that rev

as its getting up to temp it starts to doing its own thing, the revs will start climbing so i have to turn them down abit, a few seconds or minutes later it will start dropping again so im alway adjusting the revs.

right then, it moves on to another stage then where it will go up to 2000rmp hold for a few seconds then the revs drop till it cuts out.

if i turn the ruvs up to just over 2000rpm it will just catch it before it cuts out, and its pulsesating between 1000 to 2000rpm in perfect timing say every second up down up down up down etc

this problem is cooking my head could it be the dizzy or sensors maybe?

if i start it again tommorow it will do the same all over again

any sugesstions will help alot

thanks diesel

 

i forgot 2 say erst s2 mfi

 

anyone?

 

Had same with mine and it was a knackered metering unit.

 

iv got a spaire one in the garage somewere i will have to give it a try, hopfully that ones not fucked aswell i bought it off ebay about 2 yeays ago

 

Idle mixture is wrong, adjust it 1/4 of a turn at a time until you get a nice steady idle, try in both directions (lean/rich) you'll soon know what it wants
If that doesnt work then could be the metering unit itslef, or a number of other things

 

iv tryed the idle screw and theres no luck with that, it will run smooth but wont go under 1100 the hynes manual says it,s 920 to 960rpm but it will only run on 1100 for a few minuites then it goes nuts

i will change the meter unit and see how that goes

Just bear in mind when you do it will need setting up on a RR before you boost at all, as the fuelling could be anywhere!!

 

the fueling is way out now so i wouldnt hammer it, plus iv chanced the cam and chipped it etc etc it wont leave the garage till its finished and after i get a mot on it its first run will be to the RR

 

Good old rs turbos ey

 

lol if you drive around in a rs turbo and you havent got tools with you your not coming home

 

Air leak mate, pretty sure thats what your problem is, check ALL vacuum hoses especially round the back of the manifold.

Rob,

 

will do im off down there now, iv checked all the boost hosses and there fine but i havent checked round the manifold so it worth a look.
