[Coreylt1]

motor is an lt1 with cc306, fresh rebuilt, new o2 sensors

the car does not idle on its own soon as it starts, need to give it a little gas for a few seconds then it idles on its own around 1500 then could drop to 1000 or stall or even jump to 2000. the tps code gets thrown with car off key on, maf code doesnt come on until car is running. i dont usually throw parts at a car and hope it works but i replaced the tps and problem still occurs. i oblonged the holes on the tps but im a noob when it comes to ohm meters(need help) so i am not sure if it is set properly

Codes:
p0122- throttle/pedal position, sensor A, circuit low input

p0100- mass or volume air flow circuit

also is throwing this code.
p1657GM- skip shift 1-4 upshift.

i been researching for days but have been coming up with next to nothing,


thanks in advance
