The engine management system has detected a serious fault and to protect your engine from damage has put it into "limp home mode".

Whatever the actual cause is (possibly a false alarm or a faulty or disconnected sensor) the car needs to go to a garage again for a diagnostic check. Unless you have a good and up to date DIY code reader, then all you can do is to check the oil level (may have leaked or been over or under-filled). Leave the car on a level surface for at least an hour after turning the engine off: withdraw the dipstick, wipe it and reinsert and remove to get an accurate reading. You can also check to see if there are any obvious disconnected wires: perhaps the temperature gauge or oil pressure sensors were accidentally left disconnected after the oil change. Don't assume it's the oil change which caused the fault: use your vehicle maintenance guide to make other routine checks such as the coolant level. Simple checks like these may diagnose or even cure the error without needing a garage.

Is that a low oil pressure light or a silly Check Engine light? Check the engine oil level and the automatic transmission fluid level. If those are ok, it could be a bad filter or the wrong oil, possibly a bad sending unit.
BTW, there's no need to let that engine idle up to temperature even in cold weather. A minute is quite sufficient as long as you have oil pressure. Otherwise you're wasting fuel and creating more pollution since the engine efficiency is lowest at idle.

I have a toyota Camry 2000 and the check engine light is on and the steering wheel is shaking when driving over 40 mph


The shaking may be a separated tire.

If the check engine light is on there will be a code. Have the computer scanned for trouble codes to see why the light is on.
