will arm rests out of a 1985 firebird fit a 1988 iroc z ,and will you have to change the oil if you take the fuel injectors out?

 

Depends on what you mean by "fit"; yes the doors have the same hardware so yes they will bolt on, but as far as whether they will look right or interfere with something else... I'm useless. I would say probably not, unless you're the experimental type.

You don't "have to" change the oil if you remove the injectors. You might "have to" change it if large amounts of fuel get into the oil (by way of draining out of the fuel rails into the intake perhaps) in the process of changing the injectors, and the oil gets diluted by gasoline. But even then you don't "have to" change it. There's only one thing in life you "have to" do, and everything else for the rest of your life is just a matter of options and consequences. You can be the judge of all that in this case: If you successfully avoid getting huge amounts of gas in the oil, as determined by your tolerance for how much it takes to risk damaging your engine from gasoline-thinned oil, then you can change them and leave your old oil in there. Seems to me with minimal precautions like draining all the pressure out of the fuel system, you should be able to do as you desbribe. I've done it before, but I've also seen situations where the oil was definitely contaminated.
