My car runs at low speed but the car still shaking,Maintain on time, has spent three years Toyota corolla,I want to know what the shaking will what are the reasons?

There are two types of car shake
1, stop idling shaking, this situation is generally low or lack of cylinder engine idle speed. Misfiring need to check the spark plug and the high voltage line! In addition, the nozzle and the solar term door dirty is easy to appear this kind of circumstance! Wash!
2, the driving time jitter, the chassis and a relationship! Because the rod or swing arms open, do a four wheel positioning can be solved!

I would say something cut into the wiring harness. Maybe it is resting on a hot pipe, but that is a lot of circuits. It has been running rich, which may have caused the converters to fail. Do not replace them until the problem is solved and only if tbe 420 and 430 codes come back. Check the ecm connector and the unit itself for damage. The ecu looks like it's on the center of the firewall, but I'm not sure if it's inside the cabin or engine compartment.

If you replaced the distributor,plugs,wire,cap,coil,and still have misfire?Inspect the EGR. reove and make sure the pintle is not carbon up.

After the engine start running for sometime it starts shaking.

hi this could be a few things, i would check your idle as a very low idle will cause engine shaking when the engine is near stalling, idle should be around 700rpm approx when warm. If that checks out all good check the leads and that one is not getting worn and causing a misfire or a vaccum hose is not off, both will cause similar problem. The last thing i can think of is a broken engine mount causing problem as when motor idles or runs at a certain rpm it will shake harder and may be the cause aswell

Code po100 & p0300 come up. then I clean throttle body with cleaner, then the van stops missing & run good & light go's out.

P0100 is mass airflow circuit, p0300 is multiple cylinder misfire. Faulty maf sensor is most likely the cause of the misfires.

When it idles the vehicle shakes. it idles rough

It sounds like there may be a cylinder misfire... .basically a misfire is when a cylinder does not fire correctly, This can be caused by faulty spark plugs,coil packs,dirty fuel injectors,clogged fuel filter,or bad cylinder compression. When was the last time you gave it a tune-up? I would lean towards changing the spark plugs myself. good luck
