I have a 90 3.8 lx, Out of no where the Idle went extremely high (6000-7000 rpm and has stayed that way. I was only able to bring it down by disconnecting the m.a.p. sensor but now my car is shooting carbon everywhere. I replaced both the TPS. (throttle position sensor and the EGR.) but to no avail. does anyone else have any sugestions
