I did a full tune up plugs, wires, cap, etc about 4 years/ 8k miles ago. The car was sitting outside in the northeast the entire time. Should I replace anything? The engine has a vibration at idle and when going over 2500 rpms. Wasn't sure if it was the plugs or the motor mounts.
Timeframe for tune-up?

Cap, rotor and plugs for sure as they corrode just sitting in the elements. Take a look at the cooling hoses, fuel hoses and belts. They will also deteriorate with age. The gas is also probably bad causing the poor engine performance.2004 525i Manual - 1985 325E Coupe Manual -
Sometimes with duralast if you look at the label on the part it will be name brand and the box just says Duralast. But usually for parts I stick to name brand or tried true brands. But anything is better than corroded parts.Comment
