Knocking in 3.0 engine. I pulled each spark plug wire off dist. one at a time and on one cylinder plug wire off it stopped knocking what can I do?

Try spark plug wires.. Pull off one spark plug wire at a time to see which cylinder is not firing. When you find one not firing change the wire to another plug.. both ends dist and plug end. If problems travels to new location the plug wire is at fault. if it does not travel there is something wrong with that cylinder. Could be something as simple as a fuel filter. R22 is one of the best engines ever.

V6 engine: firing order: 1 2 3 4 5 6, distributor rotates clockwise. Left bank of engine (driver's side), cylinders 2, 4, 6 (#2 at front of engine). Right bank: 1, 3, 5 (#1 at front of engine).
Inline 6 engine: firing order is 1-5-3-6-2-4. Distributor rotates clockwise.
The number one tower on the dist. cap should have a mark or numeral 1 on it. If not, turn crankshaft to top dead center of compression stroke on number one cylinder, the 0 degrees or "T" mark on the crank pulley pointer. If you are on the compression stroke (not the exhaust stroke), the rotor under the dist. cap will be pointing to the number one cylinder spark plug wire tower.

Generally a Pinging noise isn't due to a knock sensor. It sounds like you may have Detonation issues.

I'd really check your spark plugs to make sure they are not fouled as well as running some higher octane gas to see if it helps.

basically, your getting combustion earlier then you're supposed to. This could be to various reasons.

Check in this order, Spark, Timing.

Check to make sure the spark plugs are all sparking and clean / properly gaped. Pull one coil/wire at a time off the plug to see if the pinging stop (pull a wire, start the car. Turn off car, re-attach wire, move onto next plug.) If it stops on a specific cylinder that means you're having detonation issues on that cylinder. If it never stops, then it sounds as though it could be timing related or have a valve train issue.

We'll start here and move on. Let me know what comes of this!

or do you want the timing for the plugs.

GET A PIECE PAPER DRAW A LARGE CIRCLE TOP UPPER HALF CIRCLE LEFT TO RIGHT WRITE NUMBERS 1 AND 3 BOTTOM HALF CIRCLE LEFT TO RIGHT RIGHT NUMBERS 2 AND 4 THAT YOUR DISTRIBUTOR SPARK PLUGS WIRES LOCATION.STANDING ON SIDE OF ENGINE WHERE DISTRIBUTOR IS LOOKING DOWN AT DISTRIBUTOR 1 AND 3 FIRST TWO SPARK PLUGS TERMINALS NEXT TO ENGINE. AND 2 AND 4 SPARK PLUGS TERMINAL ON CAP FACING YOU. THIS IS CYLINDERS LOCATIONS STANDING IN FRONT OF ENGINE.RUN WIRES FROM DISTRIBUTOR CAP TO PLUGS TO THE ENGINE SPARK PLUGS.

fould plug in 3 or 5 cylinder

STANDING IN FRONT OF CAR 1 ON DISTRIBUTOR CAP IS ABOUT 5 OCLOCK POSITION.

Is the coil connected to the ditributor? did you knock any connections off in the process? Does it turn over but not fire? do you have spark at the plugs? Are you sure of cylinder location in respect to firing order? Did you-and check this first as with any elec. problems-blow a fuse in the ignition circuit? good luck!

unplug distributor! find #1 cylinder, take out spark plug,placr finger over spark plug hole,bump starter until compression blows finger from spark plug hole,align mark on harmonic balancer with 0 mark on timing cover. engine is on compression stroke.install distributor with rotor contact pointing toward #1 wire location on distributor cap. install plug. install wire. engine will start.

after connecting your wire try resetting your distributor or pull timing chain cover and ckeck timing marks on gears
