I didn't know what to title my question....anyway....
In 1989,1990 and 1991 I drove around the country. The first 2 times I drove a 1987 Pontiac Firebird and the last time was a 1989 Ford E-150 conversion van w/351 windsor.
While going over the Rockies in CO, WY and MT I experienced a lot of engine miss and loss of power. I found out later that the computer chip was not programmed for high altitude. (Is this true???)
I'm looking at buying a new motorhome. My question is....do newer vehicles have programs to adjust for higher altitudes and air density?
