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??

Well for one the only difference in the lex afm and stock afm are the size, the electronics are the same so take the electronics and put them in your stock housing and run it like that until you get the supporting mods for the lex afm. such as the 550cc injectors, afpr, and walbro fuel pump or 2jz gte fuel pump.

As for you idle problem and rpm fluctuation check your codes sounds like your tps may be out of adjustment. your gas pedal can be adjusted by the throttle cables on top of the cam covers.
