dropping my car is300 for a spark plugs, coilpacks, plug wire replacement. Yes its expensive because its a dealership but the oem parts should be installed properly hopefully ( i dont have time plus i lack movement with my right arm in general ) . NOW my question is should i get anything else replaced ? ( should i call and order more parts there to be installed this friday ) My overall service record has been clean , and my car just hit 128k. prior to my ownership i noticed the timing belt service was done already, and a replacement vvti solenoid was installed. is there any recommended service i should have done while my intake manifold is tworn apart, or my car sitting for half a day in general.
