Default 2001 2.3L 4cyl - Replacing the spark plugs?

Ladies/Gentleman,

Having trouble even locating the other 4 plugs that are mysteriously on the drivers side of the engine. Anyone have experience with replacing these (maybe a diagram of someone who has conducted this procedure)?

Any advice would be greatly appreciated!

Thank you,

Brandon

I have a 1991 with the 8 spark plugs and it is no problem find the extra 4. My daughters 4cyl ranger, a newer modle than mine, only used 4 spark plugs. It never had the pep mine has either. Are you sure you have the 8 plug version?

Good luck !!

Default 4 plugs

I have the same year and type of engine. There's only 4 plugs in that model otherwise you'd have 2 electronic coils. I do have a really bad miss in the engine that I can't seem to figure out. I've replaced the wires, plugs, and the upper O2 sensor and it still misses. If anyone has any idea of what it could possibly be, please let me know. Thanks!

Well I went to O'rielly's to get a crank positioning sensor. The guy asked me if my check engine light was on and i told him yeah. He asked me if it was flashing, and i said yeah. Then he told me that if the light is flashing that it is the coil pack. i replaced that, $25 at autozone, and it doesn't miss anymore.

My 97 has the 8 spark plug set up. There are two coil packs, so locating the plugs is a case of following the wires. You'll need to lift the intake manifold to remove them. It's a fiddly job, but it just takes time. Make a note of all the connections, some wires go to sensors in strange places.

I'm about to change the 8 spark plugs and ignition wires on my 98 Ranger 2.5L. Besides the need to "lift the intake manifold", will I also need a flexible or multi-joint extension for my socket wrench? The Ford shop manual says I'll need a special "Spark Plug Wire Removal Tool" to pull the wires off. Since I will be trashing these anyway I'm inclined to just yank em out!
Any other tips for this job greatly appreciated.

There really is no point in replacing the exhaust side spark plugs.

They are only for emission. Save your self some money and just do the 4 on the intake side

I need to go for my Ontario "Drive Clean" (emssion) test next week. Would replacing those exhaust side plugs help the engine to run "cleaner"? I've already paid for the complete wiring kit, and the cost of plugs is minimal. Seems like the drivers side plugs are the tough ones to get at!!

I'm not positive about emission test we don't have them here in Missouri

From what I just looked at online as long as your oxygen sensors are good you should be fine.

Default Re: 2001 2.3L 4cyl - Replacing the spark plugs?

Hi, I need some help. I have a 2.3l 8 spark plug engine (1991) I've got a miss or something going on. It started as a big miss at highway speeds about 55, it would actualy stop fireing it felt like for a second and then be fine. Then it started feeling like it wasnt getting gas when I would start off, i would lift on the gas and it would catch up and run. I changed the plugs,wire and coil on the primary side. still did it. I tried to clean the maf senser and it got way werse, HA now i think its the maf so I change that. started up fine, ran around the block a few times running strong. I go to get gas today and its doing the same thing again. it wants to stall when i give it gas and when im going it bucks on and off. Im at odds.

As mentioned, the SOHC 2.3/2.5 uses 8, the DOHC 2.3 uses 4.

First, do you dual coil packs? Changing the plugs on the driver's side isn't all that bad and you don't have to remove the upper half of the intake.

Once you locate the plugs by following the plug wire, you'll need a plug socket with a universel and a 1' section of rubber tubing that will fit snuggly to the upper portion of the plug it's self. Lossen the plug to where it's almost all the way out remove the scoket and slide the tubing over the plug and remove it the rest of the way.

Installing the plug, put the porcilen end in your tubing and thread it in till you can pull the tubeing off and use the socket to tighten. Saves an hour of unnessarly removing the intake...........

A lil tip: Take some masking tape and put 2 wraps around the universil joint of the spark plug socket to keep it from flopping around, itll still have the flexability.

ive heard these are for igniting the exhaust stroke to burn of unburnt fuel. So would neglecting then actually hurt driveability or mpg or engine longevity? Bc lets face it they are a major pain in the ass to change as far as spark plugs are concerned.
