ok so i have discovered something. i have two computers for this '88 new
yorker. one was in the car already, the other i got from an identical '88
in the parts yard. SO..
with computer A) i get normal mileage, runs a little rough, accelerates
fine, and everything else is ok.
with computer b) i get really shitty mileage, runs awesome, accelerates even
better, and the rest is normal.
so what's the deal? which one is *more*
i have a few ideas.. (taking into consideration that the O2 sensor being
kaput is about the only thing i can think of that can decrease mileage by 12
MPG, and it is a new one in there already). either 1) computer A is busted
and the O2 sensor is good, or 2) computer B is good and the O2 sensor is
bad, 3) both A and B are busted and i have to get another computer as a
control group, 4) the O2 sensor is bad AND the computers are both bad, 5)
both A and B are fine, the O2 sensor is fine, and i have another problem.
thanks for the help guys ;)
