sup guys i just recently got 99 mustang gt im already havin problems with it..i gues its just all luck first intake manifold started leakin..i replaced that last night now im havin problem with throtle body cable its too lose i couldnt find any bolt to adjust it... car idles at around 1300rpm.. when i come to the stop sigh n out of gear RPM goes up to 2000 rpms drops down realloy slow anybody body know where the cable adjuster is? . or is somthing else? if anyone could help me out..i would aprricate so much.. .

 

for the rpms dropping slow, i would suggest doing the IAC mod. that takes care of the dropping issue real quick. as for the throttle cable, i have no clue. if ur car is having weired rpm issues maybe your MAF is dirty? or you might try the PEDAL MOD? that might take some of the slack out.

 

Hi. I had the same problem on mine. I was suggested to remove air intake and look to see if the flap in the TB was closing completly, it wasnt. It was full of dirt which I cleaned with TB cleaner and a cloth. Its been fine since.

 

my tb looks clean .i changed the tps last night.. but no help.....only thing helped alittle was IAC after cleanin it rmps did drop to 1000 before it would idle around 1300 1400 ....so im guessing it could be aic.

 

ok so the TB cable mal adjustment is making it act crazy? Or is it some vacum leak? Do you hear any hissing noises? That would be a leak, bad gasket.

Might want to try have the cable professionalyinspected to rule that one out first. From there it might just be a full tune up, plugs, filters.....

 

problem solved... it turned out to be..tb wasnt closing all the way..n it was messing with tps voltage...took it to this shop...n got it fixed... thanks for the replys...
