Definetly need to syphon the old crap out and fill w/ good premium or reg. If your going to advance your timing to 12* then use premium otherwise no need but check your timing to be @ 10*btdc. You will need to do a complete tune-up: Plugs, wires, cap, rotor, oil, filters, etc. Get a can of starting fluid a spray aroumd your intake while idling to check for a bad gasket or hose.
Most of the guys in here more than likely got it right when they are saying its bad gas or it just needs a nice tune up. If you already ran the gas might as well run it all out and then tune it up and change everything. Trying to syphon it out you are not going to get everything. No two mustangs are alike in throttle response. I have has some better than others. Most people overlook tps.
green to black should read .98v or as close as possible (loosen screws to adj then carefully retighten while holding in place) but thats probably not going to give it hesitation.
i AGREE i recalibrated my TPS a couple of weeks ago and i could tell a difference as soon as i started my car. the have been several threads about this subject-i would search the site so you can make sure you are doing it correctly. the car has to be off, the key has to be in the "on position" (when calbirating your voltage). then you need to start your car and recheck your idle screw on your TB. my car(5.0/5speed) is set at a 750RPM for idle, yours will vary based on year and transmission.
to add to the fuel thing, after syphoning out the old junk-add 1/2 a can of Sea-Foam to your tank and run it-you can pick it up at any auto parts store for around $8. good luck!!
