Hey guys i have a 07 SS. Car jerks sometimes while in boost and boost will fluctuate for example from 6 psi to 1 and back up . Especially when i first start the car and start driving aftr it warms up. Usually after i drive it for a bit the jerking will go away when i hit boost. I have no check engine lights for this. Did some reading saw it could be throttle body. What do yall think?

 

Just got the reduce engine and a couple codes... P2135, P1681. I cleared them with the interceptor but im sure they will come back. What do yall think?

 

Well if those two codes came up there is an obvious problem some place. You might have to check the pedal to make sure it is working correctly. From the sounds of it as well, it could be the computer being faulty but I would rather check the pedal for the resistance to make sure it's working correctly before jumping to conclusions.

 

p1681 code is no longer coming up. i got another throttle body on the way. if that doesnt help i will look into the sensors

 

Forgot to add that the car idles fine and only goes into limp mode when i boost past a certain point

 

well figured out a hose running to the throttle was being pinched. fixed it and now car hits boost like normal... Mods can lock this thread
