Trouble codes: 16, 24 and 28 - CEL during highway driving

I bought my 92 MX-3 GS 2 weeks ago and have now started seeing the CEL come on after driving on the highway. I grabbed the codes and got them in this order: 16 then 24 then 28.

Anyone know what I should check first to fix this? Thanks.

Oh ya, and when I start the car cold it puffs blue smoke for a bit until it's warm. Should I add that engine stop leak for oil or is there actually something I should look at getting fixed?

1st check the manual for what the codes are.

16 = EGR Position Sensor

24 = Feed Back system (right side)

28 = Solenoid valve (EGR-vaccum)

I took a look at it and its defintely not unplugged nor is the connector in bad shape.

If you have blue smoke, you got some oil buring.
Could be piston rings, maybe valve seals.

have you done a compression test?
