Q: Knocking

asked by on

First I let someone change the coils and plugs in my 2003 vue 3.0 and noticed that it was done wrong so I went back through it myself and after I got it together it's now knocking at please let me know what to check now I have to do this myself now because I don't have the money to get it done.

My car has 170000 miles.
My car has an automatic transmission.
