Ok - here's the problem.

Driving - went to standard down shift to pass. Big back fire and blew out the Throttle body. Accelerator stuck. Shifted into neutral. Got it home. Took Throttle body off and found the valve inside busted. Got used Throttle body and replaced. Still problems. Took to local mechanic. Codes said misfire. Duh. Did full tune up. Plugs, wires, Distributor cap, rotor, fuel filter, added fuel injector cleaner to full tank of gas. Still a jerking while driving. Took to dealership code said EGR valve. Replaced EGR valve. Still does the jerking stuff and lousy acceleration to pass or get up to freeway speed.
What else should I check? Change? Nuke?
