Hi,

Operation: The offsets on an engines crankshaft are designed so that the power stroke of one piston forces the next piston in the firing order up on its compression stroke. The firing order is derived from the design of the crankshaft and is critical to smooth engine operation If an ignition wire is hooked up to the wrong plug, there is at least one other plug that is wrong too. This is referred to as crossed wires. Advice: The best way to ensure that your firing order is correct is to replace the spark plug wires one at a time. Start with the longest wire, and work your way one by one down to the shortest wire. If in doubt, the repair guides are a good source for information on the firing order and ignition wire-set routing.

,The firing order on all four cylinder S10's is 1,3,4,2,
