hey, i just recently replaced everything essential on my motor (1991 acura integra RS) ;spark plugs,wires,distributor, etc... and the other day i was taking my car for a cruise , and when i did i noticed that the car had lost alot of power , then i took it back and realized that my brother was playing around with the motor before i took it for a cruise, so i popped open the hood and saw that the 2nd spark plug wire wasn't in, and i was driving it around with it out the whole time.... i put it back in, cleaned all the spark plugs and when i started it and pressed the gas i noticed a POPPING sound coming from the intake, and when i put it in reverse the car sounded like it was about to die.... so i took it for a cruise to see how it would handle on the road, and i stilled expericed the popping sound when i was accelerating from 1st gear to 2nd gear, the car's acceleration was soo bad and it wouldnt even run properly..... what could this problem be?????????? thank you for your time
