A misfire can be caused by an ignition malfunction, but not always. A random misfire can often be caused by the air-fuel mixture ratio being upset, so the cylinders have too much air or too little gas, leading to a power loss. That is why the guy mentioned the intake: if the intake manifold gasket is bad, the engine could **** in extra air through there and so, upset the air fuel ratio and cause the random misfire. A vacuum gauge on a manifold vacuum tap could easily tell you if you have a vacuum or air leak.
Along with that, I would recommend a check of your fuel pressure. If fuel pressure is low from a weak, tired pump the engine just won't get enough gas to the cylinders.

Hi t5here my name is don
did you replace the fuel filter since it almost ran out of gas it is likely that it picked up sludge from the tank
also gm fuel pumps get heir lubrication from the fuel if it ran dry the fuel pump could be the culprit

I would check the fuel filter first
also put about 8 oz of dextron 111 transmission fluid in t5he fuel tank it may free up sticking injectors and fuel pump and it also helps clean the system out

I know this post is old, but right on the engine theres a sticker that says use multi-ground plugs only. I read a similar problem like yours and it seemed to turn out that the spark was arcing to ground over the ceramic on the plug. So maybe it could have something to do with the single ground plugs.

AWD disabled from a sensor unit in rear differential that senses high temp. This thing is over $300. Whine is from fluid. Need to change fluid. This versatrack fluid is about $40 per bottle and you need 3 bottles. Thumping noise is from loose rear knuckle bushings. These are part of the entire rear knuckle assy. and you must replace complete knuckle.

a few things that could be happening here... When you run a tank dry, it often pulls the sediment from the bottom of the tank... this is very bad for fuel injection systems. Having it run "dry" like this could have damaged your injectors. I doubt the flooding of the engine with gas could have caused any damage that would result in misfiring. I would suggest starting with the cheapest solution first, which is Oil detergent. I prefer CD2 oil detergent. It is primarily used for sticky lifters, but can help with many simple motor issues. It costs a massive 5-8 dollars at any auto parts store or that "W-mart" store.

Make sure your oil levels are where they should be, and pour this product in the oil receptacle. Run the car for about 200-500 miles ( doesnt have to be in one trip hehe). After about 200-500 miles, perform an oil change (including filter). If this clears your issue up, great! it only cost you 30 bucks total.

If not...

Misfire is caused by 3 things and 3 things only. Fuel, Spark, AIr. These are what makes a motor fire. The second cheapest solution is timing adjustment. Any service shop like Muffler M. or Belle Tire, etc, should be able to perform this for 25-40 dollars. It is very possible during your spark plug / wire change, the distributor cap got turned out of alignment with where it should be.

While you have it at the shop, you should ask them to inspect the plugs and wires since thier hands are already on the device they are all connected to. This will remove or confirm one more possible issue.

The next step would be checking AIR. Airflow can be restricted by something as cheap as a cruddy filter, but rarely does this result in a misfire, so, even though its possible, im taking this off the table, Again, during the timing inspection, feel free to ask them to check it.

Another part of AIR is your EGR valve. This is a device that, put simply, recycles your exhaust. If your motor is dependant on this device, and it's cruddy, gummed up, or plain no good, it could be robbed of essential air and fuel. This can usually be checked with a "Code Check" at any service shop for free.

The final part is FUEL. Always the last place you wanna look, because it's the most expensive. This could range anywhere from Fuel Pressure, dirty fuel injectors, or a damaged fuel pump. Again, when you ran that tank dry, there is a possibility you pulled sediment thru one of these devices, or clogged your fuel filter. I hope, and you hope, if it is a fuel issue, it's just a dirty filter. I hope this helped.

All that is left is FUEL. This part is usually expensive no matter WHAT the

this is a professsional job to evacuate, add oil and recharge the a/c system. You couls change the condensor yourself and take it somewhere to recharge the system. You DO NOT need to replace the recevier/dryer either.
