i want to know what you guys think before i buy a new computer

[shelby2]

i am thinking about buying a new computer for my mustang. the computer is from an 89 and the problem i think it has is a bad memory. i cannot pull any trouble codes or anything from it. the car will still run and does decently, but it will not keep a constant idle. also, even with a custom chip i am getting less than 9 mpg, even with a longtube header mod in the chip. i am probably going to buy a new one anyway ($177.00) through my brothers work. just wanted to know what you guys think about this. thanks, shawn.
