i noticed on this 325is i just bought for a daily that :

the rear end wanders like a trailer swings side to side example,im doing 60mph i roll the steering wheel side to side i can feel the rear end swaying side to side like after ive straightened the wheel kinda dangerous rele..

another,the car boggs unbeleivably bad when floored, and i noticed during hard turns with heavy throttle aswell and every now and then will hop right up and go randomly,never dealt with this in the 5 e36's ive owned (may be a result of what i meantioned in my first question?plus 02 sensor may be taking a dump but ive never had an 02 kill power like that its pretty bad)

lastly why do i love these car that give me such problems hahahah:eyecrazy:shifty

its late im tired please excuse the bad grammar and confusing questions and such

The wandering sounds like Rear Trailing Arm bushings or some other bushing that is bad. There are over 15 of them in the rear end. The bogging sounds like a Vanos Seal issue. My 325 would accelerate "ok" but not great. Then at around 3000 rpm it would just take off. It was the Vanos orings that were worn out. I replaced them and it was a different car. Go to Beisan Systems website and read over what they say about Single Vanos Engines. See if you're experiencing the same symptoms

my rear wandered all over, it was a blown damper/shock only

i'll have to look into the bushings and vanos seal, i have brand new shocks from a pss9 billie coilover setup back there with 2 inch drop springs,<--that was my thought didnt make a difference with the new setup
