I have a 91 honda accord 16 valve 4 cylinder. Trying to figure out why it 's running crappy and I need to hook it up to a computer but don't have the cash to take it somewhere. Auto zone doesn't go back that far. This car doesnt require a mass air flow sensor but it runs simialar to a car that needs one replaced. Does anybody have any knowledge on these? Are they typical about anything going bad on them after about 140,000 miles? Thanks
