Questions about giving the truck a tune up
ok, so I bought the truck with 45,000 miles on it. I am not sure if it has ever had a tune up. When it is in park, it vibrates hard. Also, at a dead stop at a light or stop sign, it shudders hard before accelerating. people on here told me to change the plugs and or wires, get a new fuel filter, and clean the MAF sensor. Well, I dont know how to do anything but change the oil(which I just did). So my question is, where do I start? if i dont know anything, would it be best to just take it to a mechanic and pay for a tune up? I know it would be way more expensive, but i dont want to ruin my truck. Is there a How To on changing spark plugs? How about fuel filters? And how exactly do I clean my MAF sensor? I went to Autozone and asked then about cleaning the MAF and nobody knew what I was talking about.
Thanks in advance for any help!
