HELP!!! My car is running rough after some tune-ups I made...how can I fix it?!?!?!!!!!?

hi everyone, I have a 1993 nissan quest gxe 3.0L V6 with 81,000 miles on it. Last week I decided to change its 6 spark plugs with new ones, but before that a spark plug wire came apart when I tried to take it off. I replaced the 6 spark plugs and left the bad spark plug wire in place. The car ran rough, since everytime I pushed on the gas, the revs were barely increasing, and therefore I was wasting more gas than normal. I then decided to wash the engine with a hose and some degreaser (no pressure hose, just normal hose) and let it dried for about 30 min. I started the car and it still ran as rough as before. Later I went to the store and got some plug wires (the same ones, stock) and installed them. The car STILL ran rough!! Im thinking it may be 3 possible things why the car is running rough:



a. The air intake filter system got some water in it THROUGH the housing (I covered the air entry with plastic bags)

b. The car may need some oil change, since its next oil service expired 2,000 miles ago.

c. The car sensors and wires might have got some water, and therefore they are giving wrong reading.

d. The spark plug GAP is not the correct (I did not checked the gap, I just inserted the spark plugs)

e. The spark plugs are not working correctly.

f. Not all 6 cylinders are working, maybe only 5 or 4...and if so, how can I check if all of them are working?



PLEASE HELP!!! PLEASE HELP!!! PLEASE HELP!!!!HELP!!! My car is running rough after some tune-ups I made...how can I fix it?!?!?!!!!!?
very possible you got the plug wires on wrong to begin with, you also need to take the plugs back out and gap them properly, find out the proper firing order and get those plug wires on correctly, if all this checks out and still doesn't run any better you better take it to a mechanic, just remember, water and electrical parts don't go together especially if you don't know what to cover up before you start spraying the water around.HELP!!!

g. You don't need to be working on your car. Take it to the shop.
