Car Jerks forward

I hope its ok to post again!

What can cause a car to jerk forward while accelerating? Other symptoms include loss of HP and MPG. Recently had spark plugs and wires changed. Regular maintenance. I am about to see my mechanic and ask him to check the fuel pressure.

Does check engine light come on? We had a problem like that on an old Ford Escort and it turned out to be a dirty Idle Air Control Valve.

I have never had a check engine light come on. My mechanic told me that my fuel pressure was about 5 psi low.
