Buying a new car isn’t an option! My husband already changed the spark plugs and wires. I know it’s not the gas because it’s been going on for a while and I have used premium grade gas and gas treatment. Check engine light is NOT on. It sputters when idle or when I am driving slow, not as much when I am at 55mph. Please help!

I change the fuel pump and filter , spark plugs and wires and it still want start

I am needing to get my spark plugs replaced on my car. I was wondering if anyone could tell me a general price I should be expecting to pay to have this done at a shop.

Someone broke into my car and stole my spark plug wires, and now I have to replace them, and I need to know the firing order so I can put them back in the right order. Also any picture of where exactly the wires go would be helpful as well, because I only see 3 spark plugs, and I’m guessing the other 3 are hidden somewhere else. Thanks
