So when I start it from a cold start it sputter shakes and pops. I was reading on here that the coils might be dead. I have taken it to a store and got them to check the check engine light. they said it was cylinders miss firing. Can't remember which ones. But in other words. I was wondering if anyone could tell me where the spark plugs are located or the coils, or does it have both. Also how would it cost to replace all of them or individually.

Well I'm trying to avoid going to the mechanic. But do you know what they would be located

Your engine has both coils and spark plugs. The spark plugs are threaded into the cylinder heads, as with any gasoline engine. Your year Catera has "coil on plug" ignition, and has a coil "cassette" for each bank of 3 cylinders. There are several threads on changing the plugs, do a search.

This is a plug change on al Opel Omega, the Catera is essentially the same car:

Before you go chasing plugs or coils, disconnect the Mass Air Flow Sensor. If it runs smoother it needs cleaning or replacement.

If no change then replace the fuel filter.

Replacing them fixed my sputtering backfiring Catera. I may have only needed one or the other but I'm just happy the problem is gone. Definitely change the fuel filter, after 12 years it must be clogged. Mine was. The MAFS can be spray cleaned with a MAFS cleaner. It's delicate so treat her gently. Look on Youtube for videos demonstrating the procedure. Don't use brake cleaner. If cleaning it doesn't work you'll have to pop for a new one.

Unless there was a MAF related code, it's not faulty.

It's a Craptera. You should have married a mechanic, or at least be dating one!

How many miles?

Low miles. Not sure. What condition are the ignition wires in? Also if it real damp out, at night, pop the hood when you start the car and see if you see anything that looks like a science fiction movie under the hood. I had mice chew into my wires and had a horrible time trying to figure it out. Your wires might be dried out and cracked.

No entirely true. It could be dirty but not enough to trigger a code. Why wait until it does? After 78,000 miles I think it deserves a cleaning if only as a preventative measure. Same for the fuel filter. My car was tripping P0300, P0301, P303, P0305, P0174, P0172 and after replacing the fuel filter and MAFS they've cleared and haven't returned after 2 weeks. Changing, or cleaning if possible, the air filter couldn't hurt either.
