The only real way to tell why the check engine light is on is to run an engine diagnostic scan which will pinpoint exact problem location. Many part stores will test it for free. Most shops charge $40 which is well worth it. It is likely a sensor or circuit that is faulty.

My battery light and brake light goes on , some time goes off and on / I have a new battery and I change the altalnator


Check the battery terminals (where they are connected to the engine.) Those clamps can be loose or corroded. It happened to me and if i hit a bump or the road was bumpy, the battery cables would slide loose and the power would flicker or die completely
Open the hood when the car is off and try to wiggle the positive nad negative connections on your battery. They shouldn't move at all. If they're loose, tighten them up carefully. If they're covered in battery acid or corroded, then you may need new terminals for your new battery to connect well to your engine. Good luck, i hope this helps.

Past weekend check engine light comes on, engine sounds and feels fine. However the oil pressure is running slightly slow


Check that the oil level is full.If the oil has been in service for more than 4,000 miles, change it. Replace the oil pressure sending unit. If nothing changes, put a mechanical gauge on the engine and read actual oil pressure. Though "acceptable" low pressure is only 5lbs, I would never accept that as safe. Minimum pressure should be at least 20-25psi and normal running pressure between 35 to 45psi.
How low is "slightly low"?

Low idle and stall when warm 1991 nissan 2.4 l d21 4 cy 2 wd


I feel the codes may be the answer here, idle should be around 8-900 rpm. There are a lot of possibilities for this kind of issue and the codes would be a great place to start.
