got a bit of a weird 1, the car wants to run on 4 then 3 and just seams to be really rough changed the plugs leads cap arm inled gaskets and exhaust. also if u reve it up u get a good bang from the exhaust eney ideas would be grate

 

Have you checked the ignition coil lead ?

 

yup thear is a realy good spark from the king lead and also the leads are new

 

is it down on number 4

 

Could be the fuel is set up wrong, how did the problem start?

 

seems more like number 1 but could be 4 y u say that ?

 

gave it a reve and got a bang then it just run like it is now

 

could be a air leak, of some king? could be worth checking all the boost hoes if you not do so all ready.....

 

funaly enoughf i thort i could hear air leek but it was running fine then after i reved it up it went crap

 

Check all your hoses especially the bottom turbo 1 they like to come lose
