Question about 1995 Pontiac Firebird
Washed engine and got water /engine cleaner in my air intake and into intake manifold
Have you checked the oil? Is there water in it? If so, change it and the filter. What's fouling the spark plugs, oil, carbon, etc? Here's a chart so you can better find out:
You may just want to try cleaning the intake manifold as well. Here's a how-to:
I wish you luck with your baby. Spark plugs do seem to be an issue with that car sometimes, or at least that's been the case with ours. Same model, year, engine, etc. Try to be more careful next time you clean it. I wish you all the best.

Check your alternator see if you have a drop in voltage on your tack,then it is the problem.I too was a victim of high price tune up and still had a problem with a misfire.and cover your coil pack with a piece of rubber water run of onto your power pack .Another thing is to use a silicone spray on all wires.

I have the same car with 138+ on it. I have tried several types of plugs trying to find one that lasts longer and gives the longevity I was looking for. The 4 or 2 prong styles were not any better. I would go with AC Delco platinum. The book calls for changing the plugs at 30,000 miles. That is both schedules also. However, if you are going to due this yourself be prepared, they are very hard to get at. Obviously not in the front of the engine, but in the back, especially on the left side with the air conditioner. So if you do change them, while your there you may want to change the wires as well. Get a wire puller, it will help.
I would go with easy solutions 1st for the sputtering, try cleaning the throttle body. (changing the plugs is a good start as well, along with the wires). Fuel filter is another easy and cheap try. If you have an engine light on, you may try the o2 sensors, there are 3, also relatively easy and cheap. Note: spray bolt off or some type of loosening agent 1st, also take care of the wires not to pull to hard as to break them. There is one on each side of the engine exhaust manifold and one in the cat.
I would also recommend getting the fuel injectors cleaned, if they have never been done, its time. It's not terribly expensive.
Next you could try replacing or decarboning the EGR valve. I have found them (OEM Borg Warner) on Ebay, much cheaper than dealer.
I would go with these 1st. There are many other reasons for this issue like a bad coil pack, but honestly I would be out of my technical skill range to give you fair help. These are the things I have done along the way with my 95 firebird and it still runs strong today.
So hopefully this helps
