I know I want a Bently shop manual, but it's aadvertised as 1983-93'
I have an 82'.
Is everything going to be the same?
I noticed that other manuals range is 1974-90'

 

Get the 74-90 book

The 1983 engine is electronic fuel injection and you should have manual injection.

 

The Bentley manual covers both the CI ( mechanical) and LH ( electronic) fuel injection systems. Your car could have either one,depending on the engine and where it was delivered. 81 and 82 were transistion years, and by the end of 82 most ( in the US) had the early LH systems. The Bentley is a much better source than the Haynes or Chilton's.
