Well got tired of trying the eec test with nothing but a solid light on so i took it to the shop. They say they can't test the computer and that its fried. Can't i just buy another from a mass air, 5-speed 87-93 stang and put it in? Symptoms of car are: runs rich, bucks and misses sometimes, won't start after 15 min of driving takes 4 hours for it to start again, terrible performance and barely spins tires from 5 mph take off, and last it smokes bad when i punch it. Should i insist on buying the computer myself or let the shop charge me an arm and a leg to buy/install one? Can i install one easily? They did compression check and got over 100lbs to each cylinder so am i still good on motor? Is the compression good enough for some bolt ons?
