hi i have a quick question i bought a 90 eldorado ETC i bought it from an individual with supposedly no problems. after i put about 70 miles on the car it blew the bank 1 fuse. so just thinking something just went crazy for a second i replaced the fuse. about the same amount of miles later it blew again. so i parked the car at work till i was able to work on it. it would drive on the 4 cylinders on bank 2. when i started it to try to drive home it back fired and hasnt started since. has anyone had this problem? or have any idea of what it could be? any help is appreciated thanks Bryan gibson
