My service engine light in an 01 grand am has been coming on and off for the past 2 weeks. The dealership said that a fuel cylinder misfired both times. They also said it was the same cylinder that misfired. I can tell when it misfires, my car feels like it is going to die when I stop and it doesn't accelerate uphill well. What would be causing the fuel cylinder to misfire? I have an appointment tomorrow to get it fixed, but I don't want to get ripped off and the problem not be fixed.

With the Dealer saying FUEL CYLINDER, that would make me think it is the injector that is not working correctly. The new cars are very good at identifying what the problem is. I have seen a lot of Drivability tests with OBDII systems and it's neat to see what is going on. The computer on the car can till you if the plug is firing, if an injector is opening, how long the injector was open, and how much fuel was metered in to the cylinder. It's possible they could simply clean the injector and have it be fine but most likely they will replace it just to be on the safe side. I would have them give you as much in formation about the problem before any work is done. Even if you do not understand what everything is the service manager should be able to explain everything to you so you will understand it. Also have them justify why something needs to be done. For example if the say if this is not done the car will burst in to flames, then it's probably something that should be done. If they ho hum around something they either do not know if it should be done, or are just trying to suck you for more money. Also have them keep all the defective parts so you know that they DID replace them. Take the parts home and throw them away. That’s what they do. Unless there is a core charge (things like alternators and power steering pumps can be rebuilt, so they charge for the rebuild able parts to be sent back) but most likely they will be replacing the injector or plug. Just have them explain and justify the problem. (Why and how it is happening, the overall cause and why it should be replaced)

It could be a couple of things. A bad spark plug, coil, fuel injector. It also could be a vacuum leak or a bad computer. The codes only give a tech a good place to start more testing is to find the problem. If your afraid of being ripped off ask for a detailed explanation of why they are doing what ever it is that is causing the problem. Keep in mind that some time cars have more than one problem.

It cold be the following:
Bad/worn spark plug, wrong/worn SP gap
Bad/ loose spark plug wires
Bad/malfunctioning fuel injector
Possibly a coil but it has a coil pack so if you have 1 misfire you will have 2 dead misfires. (coil packs fire two cylinders at the same time)
That's about all I can think of given the provided info

It could be a bad spark plug. You might have to change you spark plugs. It could be that the plug cracked and is not giving efficient spark to ignite the fuel

spark plugs need replaced and/or the spark pluc wires. also if your car has a distributer it could need the points replaced.
