Cylinders 2 - 4 - 6 are facing the radiator. Cylinder 2 is closest to the drive belts.
Cylinders 1 - 3 - 5 are facing the firewall, cylinder one closest to the drive belts.
Hope this helps; and Thanks for choosing FixYa for assistance.

Get a Haynes manual for your vehicle and use the troubleshooting guide there. about $20 from amazon, auto parts store or haynes.com. This WILL save you time and shortcut this and any future diagnosis. Haynes IMHO are top notch and I like them better than some factory service manuals that fgo for $100 and more.
David, 99 Saturn, Cam position sensor codes seem to indicate a engine timing (not spark, but crankshaft/camshaft sync). Old timing belts or worn tensioners can cause belts to jump a tooth or two which can have a pretty dramatic effect. The belt could also be old/dryrot and have lost a tooth or two causing it to jump. If any of these are the case, or if the timing belt interval is near, replace timing belt, tensioner, idler roller if present and water pump. FYI, quality OEM ignition wires shold last at least 10 years. If they are really bad, you can open the engine compartment on a dark night and you will see sparks arcing between them and/or something metal nearby. We all replace wires when we are not sure what the problem is, and regardless of what anyone tells you, it only rarely solves anything unless the car is more than 10 years old.
good luck.

Im having the same problem with a 96 buick century. I wondering if its the coil packs. The plugs and wires have 8000miles of use. So i think it shouldnt be them. But same symptoms, engine code P0300.

A bad coil pack can foul out the spark plugs. I have also been told the computer might need to be reset for around $100. You must use Motorcraft OE plugs for this car to run at its best is what my mechanic told me.
