E34 525i (Auto) Surging at speeds between 55-60mph

[iamjunior7]

Hi Everyone!

I am Junior and I've owned my E34 1994 525i (Auto) for about a year now and I love this car! My E34 has been rock solid and fully dependable and hella fun to drive, especially with the little upgrades I did to the suspension... Bilstein shocks, H&R springs and overhauled suspension components (Tie Rod, UCA, LCA and all that jazz...).

So, as of lately I've been getting this really strange SURGING between 55-60MPH. I've done some research and found this article:

Once this weekend is over I'll have time to check what everyone was talking about in that post. So, I'll go over TPS, O2 Sensor and CPS.

But for now... If anyone has came across this problem please let us know what you did to solve it.

Also, I've posted a video so you can have a visual of whats happening. Here is the link:

Thanks for you help in advanced!
