How do I remove and test coils from boxer engine?

How do I remove and test the coils to see if it is working properly. since its a boxer motor and cylinder head is at the side and it looks really tight. Each cylinder has its own coils I think. How do I clean all my sensors?

If I unplug all the wires from the motor to the wiring harnesses which wires do I run to the coil to make it fire, 97 timber wolf

It does not make any sense to try to make the engine run with the engine harness disconnected (it won't work). If you are trying to TEST the coil, test it by very briefly applying 6V(DC) at the primary and check for high-voltage spark at the secondary at the moment you remove the voltage.

What is the firing order for 2007 suzuki forenza sedan 2.0 litre

Redux (firing order is 1,3,4,2 but forget that)
it's not a Suzuki J20a
nor a suzuki J20b
so what is it? , it's the GM D-tec 2.0L
its not suzuki engine, (first fact) if in USA.

see photo.
it can only be wired 2 ways, guessing

the only question is which end is #1
sorry i dont know. (no FSM for it )
if you cross 1 and 4 it will run , due to wasted spark
same with 2 and 3.
the ECU fires them not 1,3,4,2
it fires the 1 then 4, repeat see?
firing coil one fires 4 too. they are wired in series. see?
when i find #1 lug, ill post it to all d-tec pages. here.

Remove coil pack

Ignition Coil Assembly REMOVAL & INSTALLATION 2.2L (VIN G and 4) Engines
  1. Disconnect the negative battery cable.
  2. Raise and safely support the vehicle.
  3. Detach the assembly electrical connectors.
  4. Tag and disconnect the spark plug wires.
  5. Unfasten the three ignition coil assembly-to-block bolts, then remove the assembly from the engine. Fig. 1: Exploded view of the ignition coil assembly - 2.2L (VIN 4) engine shown 87952014.gif
    To install:
  6. Position the ignition coil assembly to the engine. Install the mounting bolts, then tighten to 15-22 ft. lbs. (20-30 Nm).
  7. Connect the spark plug wires to the proper coils, as tagged during removal.
  8. Attach the coil electrical connectors.
  9. Carefully lower the vehicle, then connect the negative battery cable.
2.0L (VIN 1 and H), 2.8L (VIN W) and 3.1L (VIN T) Engines NOTE: On 3.1L engines, an "Idle Learn" procedure must be performed which requires the use of a scan tool. You may wish to have the coil(s) replaced at a proper service facility.
  1. Disconnect the negative battery cable.
  2. Detach the electrical wires from the ignition coil assembly.
  3. Tag and disconnect the spark plug wires from the assembly.
  4. Unfasten the mounting bolts, then remove the assembly from the engine. NOTE: On the 2.8L and 3.1L engines, with the coil pack removed, each coil can be removed and the ignition module can be removed as well. Fig. 2: On the 2.0L engine, if any part of the ignition coil is faulty, the entire coil assembly must be replaced 87952013.gif
    Fig. 3: When the DIS of Ignition Coil assembly is removed, you can remove each individual coil for replacement - 2.8L and 3.1L engines 87952012.gif
    To install:
  5. Position the ignition coil assembly on the engine. Install the mounting bolts, then tighten to 19 ft. lbs. (25 Nm) for the 2.8L and 3.1L engines. For the 2.0L (VIN 1) engine, tighten to 89 inch lbs. (10 Nm).
  6. Attach the plug wires to the proper coils, as tagged during removal.
  7. Fasten the ignition coil assembly wiring.
  8. Connect the negative battery cable. NOTE: On the 3.1L engine, this test must be done before the engine is started and requires the use of a Tech 1® , or equivalent, scan tool.
  9. If equipped with the 3.1L engine, perform the idle learn procedure to allow the ECM/PCM memory to be updated with the correct IAC valve pintle position and provide for a stable idle speed.
    1. Install an appropriate scan tool.
    2. Turn the ignition to the ON position, engine not running.
    3. Select IAC SYSTEM, then IDLE LEARN in the MISC TEST mode.
    4. Place the transaxle in park or neutral, as applicable.
    5. Proceed with idle learn as directed by the scan tool.

Boxer van gear select problem

need to feel it ,could be clutch ,if it goes in without the running then its the clutch.But i think your problem is more like the linkage and if its a builders van,then you could have rubble dropped down inside the gearchange boot.???Boxer isnt the gearchange on the dash on this model??if so then the problem could be the linkage cable ,--they get a bit rusty and sticky and you can only buy a complete pair as one unit .Try oiling with a proper oil can and some engine oil ,and not that obnoxous fish oil wd stuff

Subaru Outback - '03 boxer 2.5L engine sounds like a diesel

heavier oil if you are not in a cold climate. but before you do that have the oil pressure checked. We used to use a can of STP every once in a while on a motor in a dodge we had... nothing wrong with it... was just noisy.

Check engine light on. 4 cylinder. Light flashes on acceleration. Sometimes idles rough. Computer scan reads random misfire and #2 & #3 misfiring. Added fuel injector cleaner but no help yet. Cleared...

There are three kinds of gasoline engine misfire scenarios, first there is the "under load" misfire and there is the "at engine idle" misfire, and finally there is misfire continuously. All engine misfires exist because one of three things has occurred. First, a cylinder has lost compression, a cylinder needs a certain amount of compression to operate correctly. Second, the ignition system has failed or is failing intermittently, spark is needed at the time of compression to ignite the fuel air mixture. Third, the fuel air mixture is incorrect, proper mixture is needed for the ignition system to ignite fuel properly. If any of these conditions occur in the engine, the engine will misfire.
1. Low or no compression can be caused by

a. burned or leaking intake or exhaust valves
b. worn or broken piston or piston rings
c. worn out camshaft
d. wrong weight motor oil was installed holding the cam followers from adjusting
e. broken valve spring
f. failed head gasket.
2. Ignition system has failed or is failing
a. spark plug has fouled or is worn out
b. ignition coil
has failed
c. spark plug wires have shorted
e. engine control module coil driver has failed
3. Fuel/Air Mixture is incorrect
a. vacuum leak at the intake manifold
b. fuel injector has failed
c. EGR valve is stuck open
d. mass air flow sensor has failed
e. oxygen sensor has failed
f. air intake boot is cracked

common problems:
1. fuel injector has failed or is failing
2. spark plug wire has shorted
3. spark plug is worn out or is cracked
4. ignition coil has failed is failing

Testing a coil on the car is pretty easy. No special tools are required. Just remember to be careful, the amount of electricity generated by your ignition system can be dangerous. If your coil is already off the car, or if you would like a more specific data-driven test, you can bench test your coil. To set up the test, remove one spark plug wire from its plug, then remove the spark plug using a spark plug socket. Next put the spark plug back into the spark plug wire. Be careful not to let anything drop into the empty spark plug hole -- very bad.
