Question about Mazda B3000

1 Answer

In the past when this light came on the problem was a cylinder not firing and the spark plug was change. Problem solved and light went out. My light is on again and this time when the spark plug was changed the problem went away for a day or two but returned. It was checked to see if it was the same cylynder not firing and it was. Over the last month, the light goes out and on at different times and I can tell the cylynder works when the light is out but stops when the light is on. Now over the last coulpe days the problem is getting worse and the engine is running rougher. What is the problem?

Which cylinder is cylinder 4 in 2008 jeep cherokee 3.7L


# 4 cylinder is the middle cylinder on the right hand bank, as seen from the drivers seat. Left bank has 1, 3 and 5 (from front to back) and right bank 2, 4 and 6.I would first swap the coil with an other cylinder and see if the fault follows. If it does, then you know that the problem must be with the coil. If it doesn´t, then obviously it is not the coil. You will need then find out if there is spark and fuel. You could have a sticking valve due to carbon buildup on the valve stem. A seafoam treadment could help in that case.

Actually, it is a bad sensor. Change your CRANK sensor and that should solve the issue. They're around $70 or so. It's located down on the bell housing of the transmission. Not terribly hard to change. It is NOT your PCM. Whoever told you that, is out for blood. LOL I hope this helps!! :) -Jason

Engine light on. went to auto parts store, they diagnosed number 2 or 3 cylinder not firing. prior to this i changed plugs and wires. then i changed the coil. the engine light went off and the gas economy...


Hello mikew564.The first diagnosis was number 2 or 3 cylinder not firing. Once you changed the coil, the check engine light went off. When the light came back on again, did you get it diagnosed again to find out if the problem was the same?... 2 or 3 cylinder not firing????

First of all, there is NO extra wire/ground on the coil/ignition wiring (see images below). The spark plugs and ignition plug wiring can be checked for arcing, corrosion, resistance and can be checked for cracks in the insulators or worn electrodes (and spark gap) by a competent mechanic.
If you are having the same issue (2 - 3 misfire), there are several techniques for eliminating the plug wires or spark plugs. Spray water on the plug wires to see if they are arcing. Swap plugs from cylinders 2 & 3 with cylinders 1 & 4. If you still have a 2-3 misfire, check/inspect/examine the coil connector pins & coil harness to the coil(s) themselves.

remove the plug from the #1 cylinder, and install it into the #2 cylinder , and put plug from # 2 clyinder in to #1 plug hole, connect plug wires, and start up vehichle, and if computer shows misfire on # 2 cylinder , then you have a bad plug, possibly porcelin insulator could have a hair line crack in it, hope that this information has helped you.

Replaced the MAF sensor - nothing. Took it to a authorized toyota shop & checked compression which check out good and put the computer on. Computer read mis-fire on cylinder 1, and then multiple misfire (like it would jump around). We went ahead and replaced the fuel injector on cylnder 1 - did not solve problem as when we hook the computer up, misfire seemed tp stay at idle and seem better when running high RMP, but check engine light is on as it never went away. Went ahead and replaced the coil pack to cylinder 1 - nothing. what am i missing?

Ignition problem car runs on two cylinders randomly


if one spark plug were fouled or one plug wire was arcing to the engine then 2 cylinders would not work, the spark is controlled by the computerif its been 30,000 or sole miles since plugs and wires were changed change them it might fix it but at least you will know it isnt that and plugs would have been close to worn out anyway

Firing Order diagram for 2006 Ford Explorer


Hope this helps. The ignition coil:
  • changes low-voltage pulses from the PCM to high-voltage pulses.
  • fires 2 spark plugs simultaneously.
  • has 3 transformers.
    • One transformer fires the spark plugs for cylinders 1 and 5
    • One transformer fires the spark plugs for cylinders 2 and 6
    • One transformer fires the spark plugs for cylinders 3 and 4
Spark plug wires:
  • carry high-voltage pulses from the ignition coil to the spark plugs.
The spark plugs:
  • change high-voltage pulses to spark at the gap, which ignites the fuel and air mixture.
The firing order is 1-4-2-5-3-6.

Engine light keeps comeing on mecanic change o2 senser worked for half hour came back on cods keep saying its miss fireing have had this problem for a month know


Start Small work to Big = Saved Money!
The Code(s) should be telling the specific cylinder(s) that are misfiring. Do you know waht the code is?
Target those cylinders 1st before testing the unaffected cylinders.
The following should isolate the problem(s).
1. Spark plugs - take out-reconnect back to wires and test spark plugs for getting sparks. If none: Don't replace them yet. GO TO 2. If the spark plugs are worn, dirty them replace them.
2. Remove spark plugs form end of ignition wires and test for spark from the wire. If none: Don't replace them yet. GO TO 3.
3. Remove the wires from the coil connection and test the coil for spark for each cylinder. If none: Don't replace it yet.
4. Test each spark plug and wires this way.
5. Coil Packs normally provide fire for 2-cylinders at the same time. The two are paired across from one another.
6. Test the coil for fire, amount of fire and if there is both cyclinders firing.
Misfire and the O2 Sensor got replaced??
Good Luck and get back with me if you need additional help or if this solved the problem.

the number 6 cylinder is located (if you are looking at it from the front of the car) it is on the left side third cylinder back from the front. you probally have a bad injector that is just dripping fuel into that cylinder.
