I just took some videos .. just noticed a weird sound it started making .. see if these help any
heres the first one .. got a vacuum line run from the nipple on the intake manifold (between throttle body and valve cover, next to the tps) to the fuel regulator and the ABV
the second one the vacuum line is attached to the intake manifold and goes to the abv (nothing attached to the fuel regulator)
you can hear some popping in the second video, and afterwards some smoke came out of the exhuast after I shut the car off
my brother was in the car and said he revved it to about 5000 rpm .. it WONT idle worth anything .. you have to press the gas / play with the pedal to get it to run and then rev it to keep it running otherwise it just dies (he lets off the gas pedal at the end of each video)
