Living in Germany and just had my 95 uk turbo serviced yesterday. Oils, filters and plugs changed. Took it out for a blast today and when i try to go on boost it almost shakes itself to death. Any ideas before i take it back on Monday ranting and raving

 

They may have damaged one or more coilpacks whilst removing/fitting to gain access to spark plugs. Over a period of time they become brittle from heat under the shroud where they meet the top of the plug which causes them to break down

Cheers
