I recently picked up a 1991 325i that had been sitting for 10 years. Things I have done or have checked to get her to this current point.
New Spark Plugs (good bosch ones)
New fuel (most of the old stuff had been emptied before storing)
New used fuel pump
Getting spark in all 6 cylinders
Getting fuel from injectors in all 6 cylinders
Timing belt
Waterpump
Tensioner
Oil change
New Chassis ground cable
New Battery
I checked for spark and fuel in each cylinder and they all checked out individually. I believe I am getting the misfire in cylinders 2, 4, and 6. I tried swapping plugs from cylinder 1 & 2 thinking it was the plugs had fouled (visually one looks black and fouled), but it still missed in 2. I also switched the wires from cylinders 1 and 2 and they neither fired, not sure if that means anything given the different timing.
I did just do the timing belt, could this possibly be a culprit? Maybe I was off by a tooth? Excuse the lil vacuum sound in the video, while I was removing the valve cover earlier I broke the line /: Could this be the culprit? It was running rough before I broke it...
