What would cause my truck to idle roughly when I am at a stop light or stop sign and to stumble during acceleration? I have replaced the tps, egr, iac, wires plugs, rotor and cap, fuel pump, and filter.

Spray around the tbi unit at the bottom. If your rplm's change the gasket is leaking and needs tobe changed.
