I was idleing my car once a day ran fine went out next dat started then stalled when it did start it had flequating idle and souns like back firing through air breather

"I started the car, it ran rough at idle."................

Hate to say it but it sounds like your timing is off a notch. I would start there, it should idle smooth, rough idle indicates timing, all other things equal. I would also check to see if you haven't pinched a wire somewhere in the system, recheck spark plug wires, check for vacuum leaks, verify the PCV is working properly, and check the air intake ports for leaks.

ned to titned the head

You can't do any testing, until you have a battery
that will take and hold a charge

Then you move on to testing the Alternator,then
Fuel Pressure & continue on with other testing

Check the battery cables. I had the same issues with my 96 tacoma, The battery cable connection at the battery can be cranked down but still be loose. Hard to explain, doesn't make sense, but just check it out.

You need to do a fuel pressure test, when is stalls do you still have spark ? Honda's fuel pumps fail and also the ignitor fail.

Sounds more like a timing problem than an O2 Sensor. Distributor out of Sync would be my guess. It ran better at Higher idles because the timing belt/chain was tight from tension at low idle the timing was off which caused your problems. Now the belt is either broken or so loose the timing is out and the vehicle won't fire. If it has a Distributor cap remove it and watch the rotor. If it turns the belt is intact but Timing may still be off.

It seems like a bad idle Air control Valve or an Idle position sensor. The best way is to get a trouble code for free at most autoparts stores and they will tell you what might be wrong.

Bad fuel, water in the fuel, dirt in the fuel.

Drain the fuel tank completely.

Pour in a gallon or two of fresh fuel.

See how it goes.

Put some of the old fuel in a glass bottle, hold it up in front of a light and see if you can see any foreign material in it...

Sound like a bad ground wire going from engine to firewall...

if this a fuel injected car just check to fuel pressure first.
