When I bought the Stang it was on empty. I barely got it 2 a gas station. It was buckin', boggin', n wanting 2 die out.. I put in 7.5 gals of high-test(93 octane). N at 1st she didnt want 2 start n stay running.. Then once she got going. The buckin' n boggin' was there still. but not as bad as before.. I had 2 drive 42 miles 2 get her home. N there were times where she would have no power, buck, bog, n would die out.. But she would always start right back up 4 me! I get her home n drive around town. N she would do the same ****.. I kinda notice if I keep the gas pedal steady n not "gas it".. Then she would drive fine! But its when I either "gas it" or moderitly(spl?) press the gas pedal. She would act up.. But not all the time.. I also noticed that when I turn my headlights on. She acts up as well.. She would Buck n die out..

Any ideas of what this could be!?!

Thanx

The first place I would look is the Vac line from under the upper intake plenum to the MAP sensor.

check fuel pressure to be high and constant,
check compression on all cylinders to be high and even,
check spark at all 8 plugs
do the rest of the tune up
