Twist it back and forth until it free up, if it tears you can buy a replacement boot.

SOURCE: What is the wire that plugs into the back of the

You leave all coil pack connectors on their respective cylinders.
Usually the crank position sensor tells, the computer where the pistons are,by where the flywheel is,as it passes the sensor.
You leave all injector connectors in their number sequence.
Every vehicle uses different ways of pulsing the injectors. Not familiar with yours

Most likely NO,to the coils and injectors being tied together.
You can not spray fuel and try to ignite it, at the same time,it has to get into the cylinder and be compressed, one cycle before the spark.

You could switch injectors,and a relative did that, earlier this year, based on your theory. Sound thinking,a lot of work and not your problem.

Might add, that while your plugs may needed to be replaced,they had no effect either. Personally, never had a plug failure in 45 years,could happen I guess.

So you buy one new coil,start on one side of engine,and walk that coil from one cylinder to the next,every time you get a 300 misfire code. Put the OE back and move the new one. Consider you may have others on their way to going bad.

Make sure you have no vacuum leaks anywhere.

Why does my 1997 mecedes benz e420 run hot when I turn on the air conditioner


Couple of reasons. You may need to have the Radiator backflushed to remove sediment. You also have an Electric cooling fan which may be malfunctioning. They (fans) often have more than 1 speed and high speed may be broken so it can not keep up with extreme heat.

Some fans use more than 1 relay to switch the fans and the second stage relay may be bad.

Overall, the A/C coil is placed in front of the Radiator and depends on airflow to function. This makes the air available to the Radiator much hotter so the Radiator is having a hard time cooling the engine. The Electric radiator fans kick up the airflow to help both systems out.

A dirty radiator, old antifreeze, etc. can affect performance.

I hope my solution is helpful. Radiator shops can service most Brands.

How do I change my spark plugs on my 2002 toyota tacoma


On the V6 engine The drivers side plugs are easy although the passenger side will require you to remove the intake boot and the coil packs, easily done with a 10 mm socket and ratchet. Disconect the coil pack connectors by depressing the plastic clip and pulling them off one by one on the three coil packs . leave the plug wires attached and pull the coil pack straight up and off the spark plug.Blow out the area around the plug with compressed air to prevent debris from entering engine when the plugs are removed. Use a 5/8 spark plug socket and a 8 inch extension bar on your 3/8 ratchet at remove the plugs. use anti seize on the new plugs, gap the plugs to manufacturer specs and install your new plugs 2. If its a 4 cyl engine its actually a bit more difficult. The intake boot assembly has a bracket that bolts to the valve cover and side of the engine and you must remove it to access the 4 coil packs on top of the engine. once again the coil pack wires must be disconected and the coil packs un bolted and removed from the valve cover to access the plugs. Blow all dirt from around plug with compressed air to prevent foreign objects or dirt from entering the engine when you remove the spark plug , once again use a 3/8 ratchet and an extension with your 5/8 spark plug socket and remove plugs, use a small amount of anti seize compound on the threads of the nes plugs and gap them to manufacturer specs before installation. Also while the coil packs are off,, Inspect them for ARC Tracing a white residue and line may form on the coil pack Tip/boot if you see alot of ARC tracing Id suggest replacing that coil pack. Especially if you have a misfire condition.

Changing Spark Plugs

First off, on this model you don't have plug wires, you have coil packs with a boot and coil connected to the pack. The boot slides on the tops of the spark plug. The good thing about this is that you don't have to mark each wire to its location.

So to replace the plugs you need to disconnect the electrical connector to the coil pack and then unbolt the two bolts that mount the pack down, then remove the pack.

Next with a ratchet, an extension and a special spark plug socket, which has an insulator inside to protect the porcelain from getting cracked, remove the spark plugs.

Next step is to replace the plug, usually I slide off the boot from the coil pack and then remove the coil from inside the boot and slide the boot over the spark plug and start to thread the plug back in. Using this method allows to you feel if you are threading the plug in right. Then with a torque wrench you would torque the spark plug to the specs for the type of engine you have.

3.2/3.5L Engine (20 ft-lbs)
2.7L Engine (13 ft-lbs)

Next reinstall the coil pack with the two mounting bolts, it is only necessary to hand tigthen the two bolts. Then plug back in the electrical connector and continue this process on the next 5 spark plugs.

To remove the map light bulbs you need to first remove the overhead console.

To do this you need to remove the screw at the front of the overhead console (which is more towards the front windshield).

Next you need to pry down on the rear of the overhead console and then disconnect the electrical connectors.

Then, with the overhead console pulled down, pull of the map light bulbholders and replace the bulbs.

Installation is the reverse of the removal process.
