I got a code reader and it gives me code P0123 which it says is Throttle/Pedal Position Sensor/Switch A Circuit High…. When I do a live reading it shows the TP% at 3.1 when closed (not pressing the pedal) and 85.1 when mashed to the floor… also I get a code P0108 Manifold Absolute Pressure/Barometric Pressure Circuit High…
Car was running but was slow to take off from a dead stop till it got to about maybe 5-10 MPH then it would pick up and go as normal. I changed the fuel pump, coil packs and wires , and all 4 injectors and seals and it seems to have made things worse because now it doesn’t want to start and if it does it doesn’t rev at all and shakes then dies…
It is a 1999 Chevy Metro LSI 4 door with the Suzuki motor…
I am attaching screen shots from the reader… Thanks for any help
