' (oil cap) '
' (4) (3) (2) (1) '
'_________________'

Your misfire can be cause by couple of things but the cheapest way that you can try to fix your car is to do a tune up by replacing:
1)all spark plugs
2)do a oil change
3)spark plug wires
3)distributor cap and rotor

note misfire can be cause by:
1.bad gas
2.spark plug and/or wire
3.distributor cap and/or rotor
4.valve adjustment
5.injector
6.off timing
7.ECM
8.bad wiring(power, ground or feed line)

Cylinder #5 excessive miss fire. Numerous causes:
Bad spark plugs, wrong spark plugs, worn cam lobe, bad injector, bad wiring from PCM to injector, vacuum leak or lean condition, bad spark plugs wires, cap rotor, low compression, stuck/sticking valve, broken valve spring, MAP sensor. To much to discuss without more details....

'86 honda accord 4 cyl...runs very rough as though missing on 1 cyl ...when removing plug wires 1 at a time each 1 removed makes engine run worse except for #1 cyl which when removed smooths engine out...


no, the plug is firing. But the timing is off. the plug is firing quite a bit before top dead center on that cylinder. The burning of the fuel mixture is occurring while that piston is on its way up and is slowing it down---dragging down the whole engine. i think you should change the distributor cap and rotor as cylinder one is firing at the same time as cylinder 2or 4. This indicates a possible carbon track in the distributor cap.

When my 1991 Deville 4.9 Liter Engine is cold it runs great. But after it warms up it misses, and is noisy and gets horrible gas mileage, and I only run premium. The EGR valve moves up and down freely, and...


The combination of heat and missing tells me that you have an ignition problem. Warm the engine as much as possible and take a water mister and mist the exhaust manifold with the water mist at each cylinder where the exhaust comes out of the cylinder. The cylinder(s) that doesn't evaporate as quickly as all the others is the one that's missing (no combustion = no heat out the exhaust for that cylinder). The next thing to do is to pull the spark plug. examine it for dirt built up around the electrode. If it's dirty then just replace all your plugs. If the plugs look good ( not worn - no contaminates around the electrode) then suspect plug wires. If all the cylinders evaporated the water pretty much the same, then your coil wire to the distributor cap or the cap and/or rotor itself is faulty. Examine the rotor cap and rotor for thin black lines running along the inside. If you find evidence of arcing (the lines inside) then replace the cap and rotor at the same time. The data you gave though sounds more like plugs or plug wires if I were to guess... For best results you should plan on replacing plugs/wires/rotor/distributor cap at the maintenance intervals suggested in the owners manual. But now that you're having these issues you should have some kind of concrete evidence before replacing these items - that is unless you've never replaced them ever before. In which case it's high time to have replaced them.

How do you set the timing on a 1998 GMC Sierra?


The timing is not adjustable and it is computer controlled, but the distributor must still be clocked in properly and static timed, and here is how it is done.

There is a mark or notch on the distributor housing that the rotor should be pointing to when the engine is on top dead center. This static timing is all that matters and the computer will be able to control the timing as long as the ignition rotor is in that position when the engine is at top dead center.

1. Place the engine at top dead center.

2. Look under the distributor cap and find where the number one terminal runs under the distributor cap, and where that position on the distributor cap corresponds with the distributor housing, and it should match up to a mark or a notch on the distributor housing.

3. With the engine on top dead center the ignition rotor should be pointing to the mark or notch that is on the distributor housing, if it is not then loosen up the distributor and turn the distributor until the ignition rotor is pointing to the mark or notch on the distributor housing, the engine should now be static timed.

The car shakes back and forth and has about one half of the power it used to have, it seems one of the cylinders isnt working


SOUNDS LIKE IT NEEDS A MAJOR TUNE UP, PLUGS,PLUG WIRES ,CAP,ROTOR BUTTON, FUEL FILTER,AND A FULL FUEL SYSTEM CLEANING,BUT IT SOUNDS LIKE MOST OF YOUR PROBLEM IS THE PLUGS & WIRES, IF THAT DOES THE TRICK ,I WOULD REPLACE THE FUEL FILTER,AND PUT SOME REALLY GOOD FUEL SYSTEM CLEANER IN IT TO HELP CLEAN THE FUEL INJECTORS, & SYSTEM, BECAUSE IF PLUGS & WIRES DON'T FIX IT ,IT COULD ALSO BE A BAD,OR CLOGGED FUEL INJECTOR,AND ANOTHER BUT LESS LIKELY CAUSE FOR A MISS ,OR A DEAD CYLINDER IS A BURNT OR BAD VALVE,OR IT COULD HAVE JUMPED TIME ,DUE TO NOT REPLACING THE TIMING BELT ON IT'S SCHEDULED TIME.

What do these trouble codes mean po306 cyclinder misfire detected .how do i fix the problem?


it means you have a misfire on the number 6 cylinder

this could be caused by a whole lot of reasons.

start by inspecting for a bad plug wire if it has them

check for fire on the cylinder with a spark test tool from local part store

if it is a coil-on-plug set-up, check the coil for fire

replace coil/plug wire as needed, replace boot on coil if coil needed, replace spark plugs

I have a 97 chevy tahoe. I changed the spark plugs, wires, distrubutor cap, rotor. About 300 miles later engine light came on. I thought maybe cheap distrubutor cap and rotor was cheap. I went to auto zone...


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.
