Hi I have a 2003 BA XR6 Turbo and when I start it, it revs to 3000rpm and then slowly drops down and then it jumps up and down from 500rpm to 1750rpm till it stalls, if I push on the accelerator before the rpms start to come down the car with idle at 1750rpms, when driving and changing gears the during the gear change the rpms will rise higher then it was before changing gears, now I have had error code come up and they are P1270 engine RPM and P2110 Throttle Actuator control system. I have checked for vacuum leaks and found the air pipe that went into the front of the turbo was undone and two other hose clamps weren't working right. Now I have replaced the clamps and reconnected the air pipe to the front of the turbo. I have cleaned the throttle body and checked for vacuum leaks which now there are none, but the car is still doing the same thing, please can someone help me for I am in a real bind and with limited funds for only on a disabled pension, and and all advice would be much appreciated.
