Hi, I have a 1992 sentra 5 speed with about 210K and the just this week started hesitating when accelerating even on idle. The engine would begin to shake, even at higher RPM it would still be noticed, but seemed to smooth out. Anyways, I tried unplugging the spark plug wires while the car was on and all them seemed to work except the cylinder which is closest to the distributor, #4 I think? When I pulled the plug out of it the engine didn't do anything, the idle stayed the same and it didn't seem like it was gonna die. So my conclusion is that something is wrong with this cylinder and I have to drive back home tomorrow which is gonna be a 212 mile trip! By the way, the cylinder does have a spark because I did the test at night and saw spark, decently strong spark too. Also, I tried replacing the spark plug too, same problem. The old spark plug seemed 'wet' in a sense and was more brown compared to the other plugs. I'm guessing the fuel injector went out?? But the other three are still working. Is it okay to drive on 3 cylinders only? I don't really wanna try and fix it because i'm getting a new car once I get home, well...a used car haha. Thanks, need help please! BTW, I don't see any smoke come out of the car either, but sometimes I get a lot of clear liquid spewing out of the exhaust.
