u think? i just bought it , a few days ago and the dealership put 1400 dollers worth of work into it with 2 new cats and new mufflers and a new serpintine belt also two new ABS moduels, yesterday the check engine light came on but went off later that night it feels like their is a misfire ( shaky when i come to a stop) i also filled up yesterday and iv already lost 1/4 of a tank its a v8 though so i ono how the gas is yet, one more thing is it takes about 4-6 seconds to start the truck in the morning and whenever i havent driven it in about an hour , could this be spark plugs
