SOURCE: lurching at low speed take off

I would start by cleaning the inside of the Mass Air Flow sensor, dirt gets on the sensor element from the air going through and causes these kinds of problems, a company called CRC makes the spray cleaner for MAF's, any good auto parts store will have it, the MAF is located in the air intake hose to the engine. Another thing to check is the throttle valve and air bypass idle speed control valve for sludge, use the following procedure I have written to perform this.
Here is the most common cause of surges and stalls and low idle, it is the idle speed control air-bypass valve and throttle valve, they get full of gunk over the miles and cause idle issues (stalls) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

SOURCE: car dies when stopping or slowing down, hesitates on acceleration

check for a vacuum leak,you could possibly hear a whistle under the hood,or you can spray starter fluid near the intake manifold where the suspect leak could be and if the engine accelerates it has an vacuum leak,try the simple things first,can also be a clogged PCV valve,it is in the valve cover somewhere and it will have a rather large rubber hose going to the intake manifold

SOURCE: 2007 toyota corolla stop accelerating, pushing gas

throttle position sensor needs to be changed

SOURCE: 2000 corolla sluggish when accelerating, fine at higher RPMs

Try changing out your distributer cap and rotor button. Let me know if that solves your problem.


Thx
