Try having the ignition module tested. It is located under the coil packs. Usually Auto Zone and Advance Auto Parts will test these for free.

Dead miss in cylinder 2


I would want to know if you have normal compression on all 6 cylinders, and if the other 5 are firing correctly.
Usually when you pull a wire and the engine smooths out, you have another cylinder miss going on at the same time.
How many trouble codes do you have in the computer ?

P0305 cylinder misfire in 96 chevy z71 k1500 5.7 vortec


i would not spend the money on heads w/out diagnosing # 5 misfire. misfire is caused by many different things. i would first start by verifying in fact #5 is at fault. start engine, with it running and using well insulated plyers, pull each wire off dist. cap one at a time. you will notice the engine missing worse each one you pull until you reach the one causing the miss. this wire, when pulled, will not change the evident missing cylinder. if it is #5, check spark, at spark plug end. stick a small screwdriver or equivilent in the removed boot, and place it a cm away from a ground source. start engine. observe spark. should be nice and blue, and ark a good inch from ground. if no spark, swap a wire and check again. if still no spark replace cap and rotor. if their is spark, make check plug. even though new, its easy to crack porcilan installing it. try another plug. if still a miss, start engine with plug removed, breifly, and compression should be evident. strong popping noise of compressed air. a compression gauge is the proper test ( 4 strokes 125 psi) but if audible compression is heard without a doubt, more than likely fine. w spark and compression seeming ok, next is possible fuel, (injector) or intake leak, leaning ouy cylinder. try this and let me know.

Hi I have a 1999 1.8 ford focus its misfiring on cylinders 1


Remove the top cover on the valve cover concealing the coils. Remove and inspect the spark plugs, and replace as necessary. Start the engine and see if the miss has been eliminated. If the miss is still there, a problem could also exist in the wires or coil or even the fuel injector, which will all need to be addressed as the diagnosis progresses. A fuel injector will cause the same type of a miss if it sticks.

  • 2 Mist the spark plug wires, and watch for evidence of arcing to the cylinder head cover. This will indicate a bad wire. If this is visible, then replace the spark plug wires.
  • 3 Turn the engine off, and loosen the wires at the coil by giving them a twist and pulling them out of the coil. Leave them on the coils--you just want to loosen them a bit to make the next step easier.
  • 4 Start the engine. Using a pair of pliers with insulated handles, pull one plug wire out of the coil at a time and watch for a noticeable drop in engine RPM. The cylinder that has no drop or noticeable decline in RPM is the one causing the miss. Also when the wire is removed, watch for a good spark at the coil to the wire when the wire is held close to the coil. This could indicate a bad coil if the plug wire checks out fine.
  • 5 Check the suspect wire with the Ohm meter, and test for continuity through the wire. If there is continuity, the miss is still present and there is no spark to the wire when it is removed from the coil, replace the coil.
  • 6 Check the fuel injectors. If the plugs and wires are good and there is a spark at the coil to wire test, then checking the injectors is the next step. If this is fine, then a compression test should be done to locate an internal engine problem. Start the engine, and remove the electrical connectors to the fuel injectors one at a time and listen for a significant engine RPM drop. If one cylinder is found to make no difference or very little in comparison to the others, replace the injector.

    99 chevy 1500 5.7 missing on 3 4 6 replaced tp, map, wires cap rotor fuel filter spark plugs injectors cam and crank sensor


    Not much else it could be you have renewed just about everything. How about the coil sets? How healthy do the sparks look? try swapping some the faulty cylinder coils around with those that are good and noting the shift in misfires. The coils get hot and suffer over time. I think if you examine the sparks from each plug in turn you will see big differences from good to poor. For safety disconnect the fuel pump relay when checking the spark we don't want any fires.

    my money would be on the coil cover, especially if it had been a long time since the last tune up. it is certainly worth trying, as this is part of a routine tune up anyways. good luck!

    99 dodge caravan #4 cylinder misfires, i replaced spark plug wires and spark plugs. Scanner showed #4 still misfiring, could this be the coil?


    It could very well be a bad coil pack,or you have low compression in that cylinder.If the compression is good then go with the coil pack,if not you may need a head gasket or an intake manifold gasket.

    if you have changed the plugs and wires you need to do a cylinder balancetest and find out what cylinder is missing after you find out what cylinder is bad check compression if it is over 100 check your injector
