HI all! New guy here. I bought a 89 mustang gt 5.0. Which sat for three years in a garage. put new fuel pump filter and throttle position sensor, and clean new fuel. I got it running and started to try to drive it. thats when the problem started. If I drive like my grandma and press down very gently on the gas peddle it will slowly pick up speed. If I am going any speed and drive it like I stole it grandma passes me. If I step on the gas peddle with more agression it starts to pop and acts like it is starving for fuel I think. It idels well so I am not sure where to go from here. Sometimes I can put the peddle to the floor and the tach drops from 3500 to 1000rpm. pops and trys to kick back in and pops some more. Does anybody have any IDEA??
Thanks
