the car doesnt want to idle very well it when it does it idles high to prevent stalling.i have a 70mm bbk t/b on it and it makes all sorts of noise whistling real loud in and out like its breathing i think it might be broken somehow?. and it goes in out of tune. one minute it will be driving good next minute hesitating and stalling constantly. the rpms while driving kind of go crazy like the computer and the gas pedal want to do two different things so the idle and rpms are both going up and down randomly.it has aluminum heads and a trickflow cam and intake.the motor was out of a 95 5.0 but has 91 computer and is all set up for a fox.im just trying to figure this out any new input would be appreciated besides to go carb
