SOURCE: misfire in cylinder 3

I recently had that (po303) misfire in cyl. 3 on my 2002 Mazda MPV LX with the 6cyl. 3.0 ford duratec engine (the only engine installed that year). 75k miles. The engine was studdering while at idle and upon accelleration. It was worse when the AC was on. The check engine light came on. I went to Advanced Auto Parts. They loaned me a code reading handheld computer. An Actron OBD II. PO303 misfire in cyl.3 was the verdict. I then got on the internet to do some research. Found that the problem could be a number of things. Coil packs and/or wiring harness, spark plugs, egr valve and/or ports, fuel pump or filter, fuel injectors etc. etc.. I decided to try what I thought was the simpilist remedy first. I purchased new spark plugs, retrieved some tools from the garage and opened the hood. Though I've performed all the other routine maintenance items like oil changes, battery maintenance, air filter etc., I never really looked for or noticed the spark plugs or their location. The front bank of 3 plugs was a breeze to change out but the rear bank....well they havn't been changed yet. Not so simple. At that point I decided that since I would have to remove the intake manifold and all the wires,hoses and etc. would have to be unattached, I might as well change the 3 coil packs and recondition the 6 fuel injectors while I had it apart. The cost and hassle of those fixes then lead me back to do what my old school, auto mechanic all his life father, alway told me. "Look at the easy fixes first". Many of us think that since everything nowadays is so complex that the fix must be complex also. Well, I then purchased a bottle of Chevron Techron Fuel Injector Cleaner. So many other brands were on the shelf to choose from. Seafoam, Lucas, Shell, CRC, STP, etc., etc.. Through netsurfing I discovered an old CARTALK Q & A. They kinda gave a halfhearted nod to the Chevron product. It stuck with me so I tried it. Within 10 miles the engine began to run better. The more I drove the better the performance. The Check engine light went off. No more misfire in cyl. 3 and no more code po303.

SOURCE: Fuel Filter location on a Petrol 2004 Kia Carnival

The fuel filter is located in the fuel tank, pump removal is required to replace. There is an inspection cover behind the front seats on the floor to gain access to the pump. stupid idea. but whats not stupid about kia.

SOURCE: 2000 CIVIC System too lean Cylinder 3 and 4 misfire Deteced

  1. P0171: This means that the oxygen sensor has detected a lean air-fuel ratio. This can be caused due to a vaccuum leak or a problem in the HO2S circuit or the HO2S (Heated Oxygen Sensor) itself. (Bank one Sensor one). This is commonly located along the exhaust pipe. It could also be a bad Mass Air Flow sensor or a bad Engine Coolant Temperature sensor. Diagnostic checks will be needed to be carried out to be verified though
  2. Well as for the other codes, it means #3&4 cylinders are misfiring. It is a possibility that the P0171 code mite have caused the others to show up. I can be wrong though. But it is a strong possibility. If the air fuel mixtue is too lean indeed, mis-firing will occur, unless it is an actual electronic and not a mechnical problem. By the way, when these codes appear, how is the engine's performance. Does it remain the same or behaves poorly?

SOURCE: 2001 bmw 325i is misfiring?

misfire happens because there is still fuel not burned in the cylinder so when its pushed out its burned in exhaust tube because the heat thats why you hear these small explosions. this caused if your sparking pluge not firing well . or there is a leak in the intake valve . in your case i advice you to check your sparking plug . if this helped pls vooote
