Changing spark plugs and spark plug wires on a 4 cyl. 1998 Jetta
I want to change the spark pugs and the spark plug wires, but the air cover stands on the way. I thought about taking that out, but is seems like a nightmare, since all those numerous bolts are baked basically, and it will be tough to remove them. Trying to reach the two inner plugs also seems tough. Any idea how I should go about removing them? Is there any tool that can reach these middle plugs? even removing the wires seems to be tough.
The second part of my question: besides changing the plugs and the wires should I also change the distributor or anything else? I have bought this car used a few days ago and I want to make sure that these expendable stuff are replaced. Thank you.

Re: Changing spark plugs and spark plug wires on a 4 cyl....
The only way to remove the wires is to take the intake off.Its not that hard mine has 250,000 on it and it comes apart fine. But you need some special sockets and then it would even out if you paid somebody capable to do it for you. the plugs can be changed I use a swivel socket and a extension. The distributor should be fine I assume you meant the cap and rotor, that is easy but the clips that hold it down can be tricky to but back on. If it looks too difficult or scares you dont do it.

If your trying to change spark plugs remove one wire from a plug, replace that plug, reinstall the wire onto that plug and move on to the next plug. You don;t need to worry about firing order unless you plan on changing the wires or the cap and rotor. Even if you where to change the wires if you did them one at a time than the new ones would be in the exact same place as the old ones and there is nothing to worry about,
hi if your talking about service then you need to find out when the timing belt was done last if it has not been done then its due.
other than that you need to check gearbox oil level change oil and oil filter change air filter change spark plugs change fuel filter check tyres and tyre pressure check lights working check washer bottle fluid level and check its working take it for a drive on a bumpy road and listen for any knocking noises if any are heard then bottom ball joint needs replacing.
i hope i have given you enough to be getting on with.
let me know how you get on or if you need further assistance ok
These are really quite easy to do just time consuming. 1. remove the air ducting from the air box and throttle body 2. remove the accelerator cable and kickdown cable(if equiped with auto trans) from the throttle body 3. remove the 4 bolts from the throttle body and be careful to not ruin the gasket upon removal 4. remove the black cover from the rocker cover(valve cover) 5. remove the 2 coli packs and the spark plug wires. 6. remove the 4 spark plugs. Use NGK or Nippon Denso plugs and gapped at .032". Let me know if you need anything else.
The coil pack on these are bad about being defective. You need to check to see if you have power coming from your coil pack. If you do not try changing it out, this produces 60k +/- volts that goes through your ignition wires, to your spark plugs and ignites the gas on combustion with the piston. If it's not giving off a spark, thenyou're not getting power to fire off the engine.
Wrong model designation ali. It's either a c230 or a c280. The 4 cyl 230 spark plugs are located under the red cover on top of the engine. The plugs are down the center of the valve cover under this cover. The coils are on top of the plugs. Remove the cover, coils, and then the plugs. If it's a 280 v6 you have 2 plugs in each cyl. The arangement there is more conventional. The coils are bolter to the valve covers and have short wires to the plugs that are on the side of the motor just below the valve covers. Be careful removing the metal plug connectors. They will pull apart if you try and pull them loose by grabbing the wire. You need plug removal type pliers. Twist the metal end and pull like a mad man, repeat 11 more times! Good luck!
Locate the spark plug cover on the engine.On some Toyota Tacoma engines, the cover is across the top of the engine. On others, it is along the side 4 cyl. Remove the cover to reveal the ignition coils and spark plugs wires. The spark plug wires are plugged directly into the engine and the ignition coils are in the tip of the spark plug wire. Remove the coil and wire from the spark plug. Twist and pull the plug out of the engine. Remove the spark plug from the cylinder well with a socket extender and socket wrench. Turn the wrench to the left to unscrew the spark plug from the engine. Discard the old spark plug and apply a coat of anti-seize compound to the threads of the new spark plug. Insert the new spark plug into the socket. Use the socket and extension to screw the spark plug into place. Return the ignition coils and spark plug wires to the engine and turn it to lock the plug in place. Repeat the entire the process with the remaining spark plugs. Replace the spark plug cover when all of the spark plugs are replaced. Good luck and hope this helps and The spark plug tension may range between 11 and 15 foot pounds, depending on the size of the spark plug. The correct tension is indicated on the spark plug's packaging.
you will need the tool made for pulling the boots off but then all you need is a 3/8 rachet ,about a foot long extension, a universal , then probably 13/16 spark plug socket <could be peanut plug depending on the manifaturer of the plugs> I recomend using bosch or ngk plugs. intake removeal is not needed ....will clear all plugs with intake on but may need to unplug a couple injectors for clearance but don't forget to plug them back in
