Default Engine missing at low idle speeds.

I had engine trouble when my engine would get really warmed up. It would start hestitating and backfiring through thr throttle body. I changed the fuel pump all injectors , everything in the distrubutor is new. I had enough and got tired of it and decided to bring it to a shop. They said powermy timing was off by 6 degree's because when i timed it i didn't disconnect a wire that i needed to to time it. I picked it up the the car ran awesome and had great throttle response and power. I got on the interstate and ran the crap at of it, and when i backed off to about 60 mph it started hesitating like it was lacking gas. Wheni get to s light or a stop sign it would let it just idle it would die out. I would then have to give it gas to get started. Once i get it started and run the hell out of it it runs strong until i start backing off or die when it gets close to idle speed. Could this be the fuel filter. I changed it about six to seven months ago when i put the engine all back together from a rebuild. Please Help !!!!! Thanks, Craig.
