The slip light keeps coming on while I drive and then goes off temporarily. Also it trembles sometimes when I am in first gear when I step on the gas or the break, but once it goes into second it is fine. Also when I turn my car on the first time of the day it does not want to accelarate at all. If I press the gas at all it starts trembeling. Once I come to a complete stop it's fine though and drives great. I thought it might be the air filter but I changed that, and it stopped for a while, but now it's back. I don't know if all these problems are related or not.

Electronic throttle assembly failure, which has throttle position sensor built into it, that is a sensor for the transmission and tells the computer where the throttle is to adjust/shift if needed. I would look into the throttle assembly.

simple test to know if the catalytic converter is clogged. Only a clogged cat could cause this kind of issue,, so as you try to go faster the problem would get worse because the presuure would have no way out. So to test a clogged cat you unplug the oxygen sensor and put in a pressure gauge. Ask the mechanic if he did this and if the pressure was well above 3psi. For you to have issues right off the line the pressure would have to be around 15 to 30 psi as soon as he reved up the motor. Or if you unplug the 02 sensor from the exhaust and drive the car and still have the same problem then the cat is not the cause. By creating a hole before the catalytic converter this allows the pressure out and if the cat was clogged the car should run better.
Personally I suspect you need spark plugs, or spark plug wires, or possibly a coil, or you may even have a clogged injector. Your discription of the symptom sounds like an ignition issue. If it only stumbles on accel but runs smooth at higer cruising speeds I would suspect possble a vacuum leak at the intake gasket or possible a clogged injector.

My point here is before you replace a catalytiic for a drivability issue only, you have to have excessive backpressure to cuase a drivability concern. Even if a catalytic was old and worn out and did not clean up any pollutants, which is its main purpose, the car would still drive just fine. It would just polute.
