Let'* cover the free stuff first. These are all good preventive maintenance items.
1 - Clean both ends of all battery cables. Remove all the bolts & rubber boots from the cables so you can find the corrosion. Clean them with a wire brush or sandpaper. Coat them with dielectric grease before reassembling.
2 - Clean the ground bus on both sides of the car. Remove the metal bar from the bus & clean both the male & female ends of the bus terminals. Coat the metal bar with dielectric grease before reassembling.
3 - Remove the coils, ICM & ICM mounting plate. Clean the top of the mounting bracket, both sides of the mounting plate and the bottom of the ICM. Coat all four surfaces with dielectric grease before reassembling.
4 – Make sure all the spark plug wires are going to the correct cylinder.
