on the gas milage will be the same from the 81thousand miles i have put on 3 different cars in 4 yrs .as long as your cruizing
now if you put your foot in it off will get you better with the valet key off but leave you withone of these
you can turn the power key on and have it take below 4thousand revs but if your above that it wont activate .since you have a 90 just turn the key on and leave it there just in case some poor sap wants to find out what you have. lastly enjoy one great car and you will find that one of these
is on your face all the time. if your like me i have to drive it everyday or i get really
cranky . hense the amount of miles i have put on my cars . watch out . you also may find that you want 2 like me so you allways have one to drive .welcome to the addiction of the KOTH ie king of the hill
