I have done everything i can think of and I still have the idle rev bounce. Plus an occasional hesitation. Today i went to accelerate and floored it but nothing happened. It just slowly picked up speed. Sometimes it bucks like a bucking bronco. I don't know what is wrong. It as been reflashed, injectors cleaner was run through the fuel system. MAF sensor was cleaned. I have an 06 SS/SC with a fujita CAI.

 

is the check engine light on??

 

No. I'm at a loss. I have no idea what to do. The dealerships are a bunch of no brained idiots.

 

Is it raining when it does this? If so, it's your MAF and it has nothing to do with cleaning it. It's getting wet. If it's not raining, then your guess is as good as mine.

 

Throttle Position Sensor, TB not operating properly? Someone posted on here yesterday about this same thing happening and that fixed it!

 

It could be your ECM, this happend to me. If the ECM is bad it will not throw any codes, and it will cause the car to spraticly act and run shitty

 

It does it no matter what the weather. How would i go about checking the TB? Removing the intake from the SC?

My dealership is retarded they wouldn't figure that out.

 

IDK, let me try and find that thread!

Ok I guess they just cleaned the TB.

i vote TPS!

 

The throttle body is right at the opening to the SC right?

Where is the TBS?

 

this may not be the cause...but put back the original intake...disconnect the neg cable for a minute or more, then hook her up and drive fer a min of 10 miles. it does take it awhile to "re-learn" the new driving/air combo. if there is no luck...it sounds like a tps. i had the same thing happen several times on my fiero gt - and it was the tps. these are very easy to diagnose. - good luck!

 

my old maxima did this....its the fuel injectors, they have a short or a clog

 

I am not gonna say it is the TPS but it is definately in the TPS wiring. If you have a multimeter trace some wires and see what it is reading at different throttle positions. it should range from .5-4.5 volts depending on how open or closed the throttle is.
