ive had acceleration problems with my mustang
ive changed the fuel filter and it still no good i have new spark plugs but i dont think that will help, can it be the fuel pump?

what do i tell the mechanic? should i just let him drive the car to figure out whats wrong with it?

When did it start having problems? Do you daily drive it? And have you run more then one tank of gas through it since it started having problems?

if you want to be said and done with it. Take it to the Ford house and throw on their IDS and they will read fuel pressure and trim...

When did the problems start happening? Was there any work that was done to the car before the problems started? Even something as simple as a tune up can mess with your car, especially if the KAM wasn't cleared prior. New air filter? Clean a re-usable filter? Battery swap?

After watching the video, I personally think that it's a Fuel Supply/Delivery issue. You're car sounds like it wants to go but it's not getting the juice.

Check to see if you have good vacuum going to your Fuel Pressure Regulator and make sure that the FPR itself is in good condition, and not just allowing for the fuel to bypass.

Make sure that you don't have any lean codes, and if you can check your Long Term Fuel Trim as well as Short Term Fuel Trim.

If you have a Fuel Pressure Tester, check your pressures at different RPM while at neutral and see if the pressure dips drastically while snapping the throttle, or while hitting higher RPMs. It may show that the pump isn't sending enough fuel to maintain proper pressure at higher engine speeds or under load.

Does the car have any trouble starting? Where it takes multiple cranks for the car to finally turn over? If this is the case it may be related to the 1 way check valve inside of the pump itself, where it's remaining partially open allowing pressure to bleed back into the fuel tank.

Hope this helps a little!

I'm guessing your oil pressure gauge doesn't work?

I checked the alternator cause my car keeps on turning off every time I remove the battery.
so I take it to the store and check if it's still working but they tell me it's working fine so put it back on and put on new spark plugs and put a new tps, the car runs normal. but I accelerate it too fast and the hood came off and hit my windshield and broke it so now I have to fix that. But now my battery keeps getting drained and it's not the alternator any ideas what the Problem

Hyper speed lol. Could be a bad battery i would get it replaced to see at least. There are many things like a running light or a short that could do it.

We all have had our happy moments. Just replace the batt. It could just have gone bad and not holding charge anymore
