Well, now i'm stumpped? I have re-checked the TPS sensor and it is set at.5v closed and approx. 5v fully opened. Cleaned the EGR valve including the intake manifold. Re-started and to my avail, problem still occurring. Car continues to accellerate like it is bogging. Now it is most of the time. In addition, it now backfires from the throttle body. I have also re-checked the self diagnosis and now no codes pop up. Engine light stays lit during check, no blinks. I have even taken the car to AAmco for system check prior to my cleaning and they discovered that the air adjustment valve only needed to be lowered due to the high and low revs at idle. Was too high. Is there something I am missing. I have also checked the injectors & cleaned. Seem to function fine. Checked plugs (ok-only 4 months old), plug wires (should be replaced), rotor and cap (ok), ignitor(good), did notice when I adjusted the TPS, it did run different(rough to back fire). No matter how close to setting I get, throttle still boggs even after I cleaned the throttle body as well(now I hear it whistling) oh boy. Help!
