It has 160,000 miles. It is Not overheating. The plugs have been replaced before, but the wires are original. This was my fathers vehicle and he had it serviced. Looks like one of the wires had a cut in it it and the mechanics just silicon-ed it up, also wrapping it with electrical tape. Shoddy work in my opinion. It sounds like it's skipping on a cylinder. Whenever i rev it up, it revs fine, and i don't feel a skip. So I started to do some investigating. Pulled all plugs, but they look fine and are gapped correctly. Found a temporary wire from my crv, which is pretty much the same thing. I decide to try to isolate where the misfire was coming from. I started pulling wires while it was running. I notice that on cylinder number 2(closest cylinder on right hand side if facing the car from the front....battery side), whenever i pull the spark plug wire AND/OR the fuel injector wire, the car would run better. If i plug it back in, it runs worse, and if i try to pull any of the other 3 cylinders, it runs Even worse. This blows my mind. I pulled the Maf sensor, seems to be very Clean and to be in good working order. Unplugged the TPS and it would idle up and better, but still seeming to skip a little.
I figured i might have gotten bad gas, BUT i figured that if it were bad gas, it would affect the WHOLE fuel injection system. I'm getting new wires, plugs, and fuel filter. Could anyone help? For some reason i feel it's the Ignition Coil, but I could Be wrong.
Edit: There is no check engine light on BTW. ;]
