    for the maf, unplug it first to see if the car acts different, if it does then its bad.

    ZZP sells the TB screen, or maybe post up a wanted ad to see if anybosy has one.
    How will the car act different?

    yeah you will notice it, have the car running and unplug the sensor, the rpms should jump a little and if you drive it will act funny.

    but if the rpms dont do anything or it dont change them the maf is bad,

    and the TB screen can cause jumpy idle aswell
