lambda adjustment - would this be necessary if the car was adjusted for sea level and is now a mile up? I thought that these adjustments were done automatically with the jetting???? (on board computer stuff). But since this car is an 87, and I’m not a car expert, I can change the spark plugs and diagnose problems, but when you get real technical on me...

Anyway, anyone with info, I'd be grateful.

Gracias!
