Having an issue with my car surging / bucking at low speed / RPM. If I’m slowly driving through a parking lot, the car will begin to surge and buck and gradually get worse and more violent until I push in the clutch and let the idle catch back up again. Then it will be ok for a few seconds until the bucking starts again. Any suggestions? Thanks in advance.

mine does this at low rpms too but give it a little gas and it's fine...I assume it is normal up to a certain point. What RPMs does it begin/end at

Mine has done the same thing since I installed the e-cam. I attribute it to the lumpy idle. I'll change it out eventually.

how old are your o2 sensors? My car was acting like that and new O2s fixed it.

Looking at your mods, a dyno tune with a custom chip will solve all your issues with bucking at low speeds, I had mine done last week and I could not believe how much smoother it made my car.

Mine has been tuned and still does it. At low rpms the cam is wanting to lope as it does at ilde. That is why I think it does it

My car is having the same issues but haven't tracked down the problem yet. Yes I realize this post is several months old! Car has fcam with ported stock heads and intake.
