Post buckling under partial throttle

I notice the car running around 400 C. Also the car seems to buckle a bit while accelerating, in boost but not under full throttle. Does this have anything to do with disconnected O2 sensor? Thanks in advance!

I have a similar problem. My mechanic is replacing a faulty O2 sensor, which he tells me will fix the problem. He put mine on a 5 gas analayzer to determine the fault. No O2 sensor or a bad sensor will cause the car to run lean or rich or both!

Are you runing a 1 bar boost spring? Does the bucking act like the fuel is cut off a sec then it starts to pull again. You might be triping the over boost switch which is suposed to trip at 1.1 bar but some say are a problem. I have experanced the same problem and have just received an adjustable switch set at 1.4 bar from Shelby Suppercharger to correct this.

I have only had the car for two weeks. My mechanic told me I have a 1 bar spring. Once I get the O2 sensor fixed I will be able to tell if that was all it was. I will let you know when I get it back how it runs.

To test if it is the over boost switch you can remove the wire to it and set it to ground. If the problem goes away. You got it.
