Harse running - Peter D
Golf 1.8 MK111 Driver Monotronic single point injector.

After a local VW agent rebuilt the gearbox due to failed diff cluster bearings the noticed the throttle body to manifold rubber gasket was slit and changed same. Since this the engine feels a little rough both cold i.e. in choke mode and when running at normal temps the engine continues to feel slightly harse when on the cruise.
The garage had rechecked the engine and run some diagnostics but no fault found. I've run a tank of loaded injection cleaner and different fuels. Tick over and starting are perfect, and fuel consumption as before 34/37 mpg. Lambda probe tested OK and all pipes etc are correct. Any ideas welcome Thanks Peter

Check that the injector unit bolts are tightened evenly and to the correct torque. Sounds like this is problem, if the new gasket isn't seated properly this would also cause a problem.
