lumpy Idle can be caused by the Crankshaft Ventilation thingy on the back of the Engine block. I had a fault ignition coil that caused a lumpy reving for weeks before it finally died and showed up on the Faultmeter. Sparkplugs and Lamdba´s also are possible candidates for causing a lumpy idle.
How much did you pay for the whole repair? How much milage does the car have?
Ups sorry, 101miles
