1990 BMW 735 il e32 miss
Well fellows I hope this isn't the end for my Beamer. I have a 1990 735il e32. I parked it last week in order to replace the cv joint and the rubber dampener on the drive shaft which I did successfully. When I parked it it had a small hesitation that may could have been a light miss. After the driveshaft overhaul I was putting the muffler back on and accidentally pulled on the o2 sensor wire but did not break it. So I thought nothing of it and putit all back together and went out to drive it. It drove fine but still had this annoying little miss. Well after draining the capacitor out of the computer by connecting the two battery cables and playing with plug wires and pulling plugs and putting them back in the Beamer is running pretty shitty. Rough idle and acceleration sounds like it's drowning the motor out. One other thing I've noticed is that the exhaust will push a piece of cardboard off the muffler and then suck it back up against it. My dad believes it's the timing Chain has jumped but is not sure. I've got a new 02 sensor but I'm not sure if it will fix it. It has a new distributor cap and rotor button on it so those possibilties can be eliminated. However I have been mixing and matching old plug wires. Any ideas I hope this isn't it for my baby however she does have 250,000 miles on it. Any ideas would be greatly appreciated.
