I just installed a 65mm t body on my 93 GT. Does anybody remember how to set the idle? At first it idled at 1500 rpm's and I disconnected the IAC connector. It ran at about 900 to 1000 rpm's for about a week,butnow when I go to start it it will run at 1500,1000 or it will just surge from like 500 to 1500 whatever it feels like doing on that particular day. Thanks appreciate any help.

 

is the throttlebody completely closed b4 u turn the car on?

 

I don't know but I can check.

 

take off ur intake tube and look, it should be completely shut when turned off, if its open wen off, its gunna let more air in wen on, theres a lil pieace up top of the TB u can use 2 adjsut it
