7gmte throttle body swap

[vbryanv]

thanks for the help. had another question? i install the lex maf due to the fact that my stock maf went bad. i had bad acceleration till i got past 2500 rpms. now that problem is cured but i have another issue. my idle will not go below 1000 rpms unless im in gear and when i come to a complete stop or take the car out of gear the rpms fluctuates between 1000rpms and 1700rpms and the gas pedal is very sensitive. i'll have no pedal for 1/4 inch of travel and the all of a sudden bang. i took a look at the throttle and none of the adjustment screws come in contact with anything. even when they are maxed out. i did not have this issue before the maf going bad. any sugestions??
