Spark Plug on a A4

Autoparts store will look it up for you. For longevity, OEM are platinum. If you don't mind changing them more often, copper plugs work very good. On tune 1.8T (or chipped), I recommend NGK BKRE7E (one step colder than stock) copper plugs, gapped to 0.028 or 0.030 (B5 A4 have weak coils and they 'fade' with age; if misfires are detected, time to change coils (temp fix: even smaller gap).

06 Cobalt LT 2.2 misfire on #1 cyl. Local parts check code

misfires can be caused by plugs , HT leads and coil/s-- AND--- bad injectors, low fuel pressure. Pull the injector for no 1 and have it checked t may be the injector or the wires and connections for that injector. Make sure that the HT leads are not touching each other as it may cause a misfire on the cylinder as well

Hello, I am having Maruthi Omni LPG, for the past 3 months I am facing vehicle jerking problem due to misfire. I changed the Ignition coil ,but now also the problem arises

Th engine must be prroperly tuned for the LPG if this was fitted externally . If this was factory fitted please get a proper fuel setting done on the gas , check the spark plugs , the intensity , and also the timing.

1999 ford escort I changed the plugs, but broke a plug cap. Bought a generic replacement spark plug wire that had to be modified to fit into the head. I cannot get the firing order correct. The car...

Remove the plugs from the head. Insert into the coil wires. Make sure they are properly earthed on the engine. Crank the motor and check for spark at each of the plugs.
Refer to the diagram. Cylinders are connected as shown on the diagram in blue. 1 goes to cylinder 1(sparkplug furthest from coil pack), 2 to 2, 3 to 3 and 4 to 4(closets to coil pack).
To test the coil pack use a digital volt meter. Measure resistance between coil towers for coil 1(marked 1 in red on diagram) Value should be between 12000 and 14500 ohm. Do the same for coil towers 2.
Measure resistance between I and C1. If the measurement is more than 5 ohm the coil is defective. Do the same for I to C2.
Measuring voltage at I(Ignition start/run) to ground should be 10V.
I is connected to the 15A engine fuse. The radio interference capacitor is connected between this line and earth at the coil. Disconnect it to see if it cures the problem.
C1 and C2 connect to the powertrain control module.
Bear in mind that aftermarket coil wires may cause problems with misfiring, so see if you cant find an OEM coil wire to replace the broken one before replacing anything else.

These engines use platinum plugs-you don't gap these type of plugs because you will damage te platinum electrode and cause misfire problems. Make sure you use bosch platinum factory recommended plugs and if he vehicle has more than 75k i would recommend replacing your plug wires as well/

Replace spark plugs with plat core plug

Platinum plugs are NOT recommended for the Echo. The heat ranges are different. Put the right plugs in it (buy them from a Toyota dealer) and see if your problem vanishes. I get this quite a bit, customers put in new plugs, and it runs worse than it did before they changed the plugs. Note that ALL Toyota engines have a specific plug engineered for each engine. Platinums do not work unless the engine was designed for it. Same with iridium and NO Toyota runs well on the "split fire" plugs. If the problem persidts, change the coils around, see if the misfire "moves" to a new location, and you get a DTC P-0300, P-0301 and P-0302. If so, your coil pack may have failed, BUT, do the plugs first.
