ERRATIC IDLE

I have a 1994 Mustang GT 5.0, 5 speed trans.I addedthe ford 303 camand roller rockers, 1" intake spacer, and BBK Headers.
Ever sinceI did these changes I cant get the car to idel. Ithas a erratic idel up and down. Sometimes it will but 9 out10 times whenI pull up to light it will die.[:@]

Anyone have a suggestion?

RE: ERRATIC IDLE

try cleaning you IAC and MAF sensor. there could be a number of reasons why it wont idle but also check for any vacum leakes.
