If the mustang is stock 750 rpms, not stock at least 950 rpms.Did you adjust the Idle screw?and check the tps?Is your alternator charging?

Ok i checked the TPS yesterday..the best i could get it adjusted was .895,there isnt really much room to adjust it i mean i could oblong the slots more..i raised the idle slighty...it seems to be better but should i get the TPS to..980 or is it ok were it is?..The Alt seems to be charging fine...i think...lol..I mean its been really cold here in the teens every nite and it starts every morning...So i hope the Alt is ok...Should i get a new TPS or what?
