Hey all! new to the forums, thought id ask some experts about my car. I have an 06 Lancer ralli, turbo that was aftermarket and I just bought it used.

When I want to really get going and put the pedal to the floor all I get on my boost gauge and feeling from the car is a stutter, the gauge just jumps around until I let go, and the vehicle seems to bog down.

The turbo and boost holds fine until stomped on, if i slowly raise the speed to the floor it handles fine.

I do have a check engine light, for an 02 sensor, im unsure of which on it is.



If anyone has any input it would be GREATLY appreciated.

Thanks!
