What does rec tune up and system decarb mean?

Could you help me understand the other two that have dollar amounts on them because when I asked the guy about them, the charge you explained he specifically said that it had to do with spark plugs and wires to them being burnt. And I brought my car here because of transmission slipping again also and earlier that morning before diagnostic was completed, he told me there were some issues with transmission and he would have to order parts, but they were covered by my warranty. And it says nothing about that mind you I have had car less than two years and had it worked on three times cause transmission and I've driven since I've owned it less than 7,000 miles. I bought an extended warranty for power train, and I believe they are taking advantage of me.

My car was running so well when I tested it my friend didn't know it was on when she got in. Then I was ready to sign paperwork and the Honda dealership where I got it from told me that they had taken it to have it detailed while we did paperwork. And when it was all done a friend drove my new car home for me and the car at that point was slipping and jumping, shuddering and growling the whole way home. And then the dealership had already closed for the night. So, at 8:00 am my car was there when they opened with me upset. And I was given a renta car for next 2.5 months until the work was done on my car basically because less than two days after the first return it was taken back and had to battle with Honda to up hold their part in contract because I wasn't waiting a month to pay for it to have warranty work done on my extended warranty and got more run around tell my dad said if they didn't honor their contract we would be out front with signs until the did so this car has been a nightmare for me and still is.

Can anyone tell me how to approach this today?

Thank you so very much and I will do exactly as you have suggested. Thank you

Well, it turned out that the service sales guys wrote the invoice before the mechanic even ran the diagnostics, and the way he set the invoice up was above and beyond misleading; since he told me most of suspension was covered.

And the manager was such a fake jerk and basically dismissed everything because I didn't have time to wait for him to finish up his boy's discussion when we got back from test drive with mechanic, which he was awesome the mechanic guy gave me details on everything he did and explained until I understood. And unknowingly told the truth which got his sales guy in another lie. So only question for us is they explained because my battery was out of my car a few that the computer has to be reeducated now does that make sense to you?
