What is a spark plug range - 1997 Acura CL

Fuel pump dies around 130k.

Inspect the electrodes and ceramic insulator.

• Burned or worn electrodes may be caused by:
  
  
  
  
  
  
  • Advanced ignition timing
  
  
  
  • Loose spark plug
  
  
  
  • Plug heat range too hot
  
  
  
  • Insufficient cooling
  
  
  
  

• Fouled plug may be caused by:
  
  
  
  
  
  
  • Retarded ignition timing
  
  
  
  • Oil in combustion chamber
  
  
  
  • Incorrect spark plug gap
  
  
  
  • Plug heat range too cold
  
  
  
  • Excessive idling/low speed running
  
  
  
  • Clogged air cleaner element
  
  
  
  • Deteriorated ignition coils
  
  
  
  

2.


Check the electrode gap (A). If the gap is over the standard, adjust the gap with suitable gapping tool.







Electrode Gap




Standard (New):


1.0-1.1 mm (0.039-0.043 in.)












3.


Replace the plug at the specified interval, or if the center electrode is rounded (A). Use only the spark plugs as listed.

It is a bit of a chore, but no real tricks involved. Just lots-o-tight spaces.

You will need a few special tools, including a slim profile spark plug socket.
I used a Stahlwille socket#51, a 16mm socket with rubber insert.

A T27 Torx bit and a Low Range torque wrench (for the Torx screws- 8Nm),
and a regular range torque wrench for the Spark Plugs (28 Nm).

Another tool that made the job easy, was MB part# 110 589 01 01 00, aka
Hazet # 2771. You use the wrench to pry the spark wire off the plug.

Other helpful items were 3" and 5" extensions, and a U-Joint.

In all, it took around 3 hours. A preatty straight forward procedure.

Although the coils and plug/block areas ARE marked with A & B, I was paranoid, and just did one plug/plug wire at a time, JUST IN CASE!

Use AC Spark plugs, but you'll get a selection of them at the auto parts store, ranging from standard AC Spark Plugs to the Platinum Tipped Spark Plugs.

Try the Platinum tipped ones to get up to 100,000 mi. per plug.

1.Just use a spark plug range, but you must remove all the ignition wires. Put a label or number to each of the wires, so that you will put it in their proper places after you change the spark plugs.
2.Using a spark plug range will get the plugs deep in
the blocks.
3.Before you install the replacement plug, you must adjust the spark gap of the plugs to the thickness of
a hacksaw blade.
4.After installing the spark plugs, replace the ignition
wires to it's proper places.
5.then, you can get you car to start.

what have you replaced with your tune up? should change plugs and plug wires, as well as the fuel filter, and air filter. the plugs should be set to factory spec.. be absolutely sure you've got the correct wires going to the correct plugs. the coil packs are a pain to get to but if all else fails, it may be time to replace them.

Yes without the cam signal it doesn't know just when to fire the respective spark plugs

resistor spark plugs make zero diff in the way the engine runs, they supress radio noise only, this electrical noise can interfere with the cars radio and other electronics.
