Question about 1999 BMW 318 ti

Spark plug wires

What's the correct sparkplug wires set-up for my 1999 318ti?  I remember when I pulled the old ones out, it's simply 1234 from coilpack and 1234 to the cylinder (the plastic plug wire guide will limit your choices, base on the length of the wires)  Someone mentioned a firing order of 1342 which looking at the top of cylinders (plugs off) is pretty much correct(the outside two cylinders are at the same height and two middle ones are same).  Is the coil pack is taking care of the complicated sequence by simply following 1234 or the length of the wires?  Thank you

    Thanks for the help.  I'm currently on the road but i will see my car later today.  I will follow the order as you mentioned, I hope I don't run to having short wires as the coil pack is arranged as 1234 or vice versa..   Thanks for the help.

    Correction on the firing order.  I followed the 1342 firing order, but it didn't even start.  I put it back to 1234 from coil and 1234 to spark plug and it run like a champ.  I figured electronic ignition takes care of the firing order.  Yes it is still 1432 but is all taken care off by the computer or something.  Plus the wires comes with railing to where it leaves you no choice but one way.  This is for a 1999 318ti.  Thanks for the help

How do i check of sparkplug misfire on a 2003 ford taurus


Go to Auto Zone or O'Reillys and have them hook up the code reader. The reader, if there is a misfire, will tell you which cylinder is not firing. That's your culprit. The firing order diagram is available online or in the store. It will tell you which plug is which.

Replace the plug. Ensure the gap is set correctly. That should be the end of it. If you really must visually inspect for spark then after pulling out the plug, re-attach the spark plug wire. Hold it by the wire end, where you are touching rubber to protect from shock. Have someone turn the engine over slightly. You wont have compression in the engine as the plug has left a nice size hole on the cylinder. But a turn or two of the key should produce a spark or two on the plug. If you dont see a spark, you may have a bad plug wire.

I'll bet you a $3 bill that your trouble is fixed back at step one. Replace the plug.

Are the heatsheild on sparkplug wires attached to sparkplug wireboot or attached to head some how I dont want to mess up wires


They usually aren't attached per se, they fit in a socket that is snug enough to hold them. But the spark plug wires trap them into position. So you can go ahead and pull the spark plug wire off.

One thing to remember, when you go to replace the spark plugs you won't be able to see if they are cross thread in their hole, so DO NOT use a socket until you are sure the are properly seated and not cross threaded.

I need to know the correct way. in which to remove spark plugs


Well you need a Rachet set with a spark plug socket for your Car. Then place the socket on the spark plug after removing the wire and turn counter clockwise to remove it. Counter clockwise is turning left if looking at a clock. Be sure not to break the spark plug wires when removing them. You must hold them tightly at the end and pull them off slowly and carefully. Once you have the spark plug end of the wire off,, put it aside but remember which spark plug it goes too. It's very important not to mix them up.

When putting your new spark plugs in be sure to set the gap correctly or buy a set of spark plugs with preset gaps. Then place the new plug into the hole and turn them clockwise to tighten by hand at first them with your sparkplug socket and rachet until the new sparkplug is snug. Not to tight. Just snug as it will tighten a bit more on it's own. Then replace the spark plug wire carefully.

Tuned up car changed 02 sensor full tank of fuel still running rough


Oxygen sensor only report the condition of the engine the rough running condition can range from a worn sparkplug wires to worn sparkplugs to valve problems to injector problems. with the cadillac deville a tune up should be the first attempt to smooth the rough idle with the inspection of the cap and rotor cap and rotor do have a tendancy to arc internally and create misfire so does sparkplug wire that can leak spark voltage to ground and create misfire. the spark plug wire especially if they are brittle and hard can create issues

How to change spark plugs


Those are as easy as they come these days. Mark each spark plug wire with a piece of tape with the cylinder # written on it, so as not to mix up the wires. Remove each spark plug wire by firmly grasping the wire by the boot (do not pull on the wire) and twist it back and forth a few times while pulling slowly. It should pop off without a great deal of effort. If it is seized and it breaks, you will have to replace the wire, or at the very least replace the terminals (if you can get some). Use an air hose and blow around the base of each spark plug to dislodge any loose dirt that could fall into the cylinders (not absolutely necessary, but a good idea). Remove each spark plug with a spark plug socket and extension and ratchet (I forget which size socket, it's either 5/8 or 13/16). Check the gaps of each new spark plug (typically around 0.035 in). re-install each new spark plug by hand (do not cross-thread them) and once you have ensured that the plug is threaded in properly, tighten the plug until it seats, and then tighten an additional 1/16 of a turn. Repeat this for the remaining plugs. Re-install wires to the corresponding spark plugs. You're done!

What is the best way to change the spark plugs?


The coils will need to be removed first, then take compressed air and blow out the spark plug tubes, then you can replace the spark plugs. Use only Motorcraft Platinum Spark Plugs. Unless you know what you are doing, I would recommend a repair shop.

How to change spark plugs on 2003 camry


Find out what your spark plug gap is, and the size of plugs you require from your owners manuel. Purchase a Spark plug socket for your rachett (also a rachett extension if you dont have one) And a set of Gap Measurers. Pull out the spark plug leads from the base making sure you don't pull on the cable (can damage the lead if you yank on the cable instead of the boot) and then screw out the old sparkplug and check for damage/wear. Set the gap on your new sparkplugs and screw them back in using a torque wrench for the final turn or if you don't have one only hand (do the final turn without using the rattchet just grab the wratchet extension and twist with your hand).
