Hello all, can you help my Scoob isn't well when the engine is hot or cold it has the same problem. Before I come onto the boost it judders and the engine seems to struggle. It feels as though it wants to cut out but doesn't. The revs don't drop it just starts kangarooing and there is a popping sound as if there is detonation in the decat part of the exhaust?

I have no idea as to what this is and don't want to have my pants pulled down by the garage?

Any ideas?

 

anyone?

 

Would an additive help clean the system?

 

There is a few area to check, starting from less expensive way first, check all the 4mm hose see if any come loose or splite especially where they join to the T-peice ( if splite, just cut the bit off and re-join )in the area between the boost solenoid and the Turbo, then go on to spark plugs, lead, then to the more expensive item like coil-pack or the boost solenoid.These are the things that most likely cause the problem. Hope that's help.

 

Thanks I'll check these and see what happens, cheers for the info!
