My rs is being a pain in the fucking arse if u touch the throttle when u go to start it it then won't start it won't idle properly and u have to keep it revving when u come up to junctions and if it stalls it won't start again help I'm pulling my fucking hair out cheers

 

Air leaks, metering head could be a number of things!

 

Wat as in boost leaks

 

Check ALL your hoses are on properly and that theres no leaks anywhere!

 

you could try the idle screw on throttle body

 

air leak or overfueling, has it got a dump valve as they leak like sieves

 

Yeah got bit of oil coming out of dump valve

 

Also kicking some White smoke out I have just by passed water cooling in turbo
