My 1998 Camry gas pedal sticks in stop and go traffic. Is this part of the recall issue?

no recall for air bag the only recall for that car are for the gas pedal

Sometimes a low battery or dead one can erase idle parameters in the computer memory. Also for 2002 to 06 the electric throttle position sender at the top of the gas pedal is very slightly adjustable. Loosen the nut and see if there is enough slot there to bring your idle up a hair.

Either your throttle cable or throttle plate is sticking. This most likely do to moisture on the cable or in the mechanism freezing do to the cold.

Being that you have a 1998 Toyota Camry, these cars are fuel injected and shouldnt need the gas pedal depressed to feed fuel to your engine. It's possible you may have a dirty fuel pump or dirty injectors. Here are some possible steps (cheapest in $) so follow these in order to spend less money.
- Run some Lucas Fuel System Cleaner (green cap bottle), do two treatments of that in your gas tank and see if that makes a difference. Dirty lines and clogged injectors are caused by cheap gas and or constantly running on Empty thus allowing fuel pump to pick up sediment from bottom of gas tank.
- Sputtering could also be worn spark plugs (too big of a gap) and or faulty spark plug wires or both.
-Timing chain issues usually occur if you hear a constant vibration near the top of the engine.
-Transmission issues would be having trouble putting the car in certain gears, or the transmission stick does not sit in gear properly (slippage).

Just some suggestions that may help with your problem.

check plug wires factory wires are year dated must have to have a major missfire before turning on ck eng light most of the time the light will flash when missfire gets bad enough

the idle air control motor is sticking and need to be replaced

you are probably thinking of a master or slave cylinder going bad making you unable to disengage your clutch.( very unlikly on an 09 ) even if this happened, you stiil have control of the gas pedal, and could pull the shifter into neutral as a last resort, im almost beting you heard this in traffic court

Spray some WD-40 down the accellerator cable, I'm willing to bet it is starting to rust up
