I have a 1991 BMW 318is, 145k, 5 sp. trans.; A few weeks ago it started to miss when accelerating, but would run smoother when pressing the gas gently; as soon as I'd floor it, it would bog down and run as if on 3 cylinders. I replaced the plugs, fuel filter, air filter , checked the fuel pump for psi pressure, it read OK; I just replaced the spark plug wires, and it ran almost normal, but after a few minutes, it started to sputter, and back fired a little. Any clues? your help will be greatly appreciated. That's my only car, and can't afford to miss work. Thank you!
