Re: location of map sensor 1990
Are you from California? I am not very good with city/states - you may not have a map sensor, but a mass air sensor that was equipped with only California Emissions rangers that would be inline between the air box and throttle body. Would have been nice if they followed suit all over the U.S. - that computer is somewhat desireable for those wanting to run modifications that do not work so well with the speed density/map systems (because of changes in engine vacuum).
