Thank you for holding Jarrett,
The common cause for the type of jerking you are feeling on this 2003 Impreza is usually due to a binding CV joint in one or both of the rear-drive [axles](/topics-axle/) or in some cases excessive play in the rear differential. At either rate, this could result in a fairly expensive repair. I would insist on this being checked and repair before you consider making this purchase. If the seller in not able and or will willing to do this for you then you would be very wise to take the car to your trusted mechanic and have a complete prepurchase inspection performed to verify this is not a major repaired needed.

Okay, so this is what I could be feeling when hitting the gas? It doesn't seem to do it unless taking off

Yes, your only feeling it when taking off because you are likely taking up the slack if in fact, the axle is the cause. I would have it inspected first before you consider this purchase.

Hi, I talked to the seller he said it dosent jerk under normal driving conditions just went giving it extra gas, could the [fuel pump](/topics-fuel-pump/) just be the culprit?
Ronnie

It's not likely a fuel pump concern if the engine runs with full power under load Jarrett, If it does not then a fuel pressure test would need to be done while the problem is occurring.

Okay, and what about the possibility of a vacuum leak / turbo leak causing the jerk?
Ronnie

If you had a vacuum leak or a turbo leaking the check engine light would be on and there would be fault codes set as well.

If you do not have a check engine light on then the problem is not likely with the electronic engine control system.
Still not sure what you need?
Have a certified mobile mechanic diagnose what's wrong with your car, at your home or office.
