1995 740i problems.....any one had same

[dotcomdan]

well i just bought my 1995 740i and a couple days later it started idleing rough and losing power when i stepped on the gas and the service engine soon light came on....so i took it back to the dealer where i bought it and he took it to the shop and they ended replacing the mass air sensor and the 2oxygen sensors......it ran good for a couple of day and then it started doin the same thing,the light comes on and it runs rough then it goes out and it runs fine again......anyone had the same problems?........please let me know.....thanks......the mileage is under 81000
