They're not all that bad, change all eight plugs and wires in about an hour +/- without having to removeing thr upper intake. Just have to be a wee bit smarter than what your working on..............

they are easy to get to with one swivel, just by removing just the throttle body only. wires are different story, Use channel locks to pull the wire (by grabbing the boot)...

Same as mine, why remove the throttle body to change the spark plugs on the driver's side? Were you refering to the upper intake manifold? You don't need to R&R the upper intake period. Check my earlier post on this I've changed the plugs 3 times, Since '99, using the the 3/8" rubber tubing and I haven't removed anything. Save time and money.......

I'd get rid of that stock intake, air filter to thottle body, and install a K&N cold air intake You'll pick up 10 / 15 ponies. Also a Helex thottle body spacer between the Throttle body and upper intake, another 3 / 5 ponies...........

The less your engine has to labor, the gain in horsepower, better gas mileage.

that pic isnt my engine..

ASE here, the book calls for removing the top half of the intake plenum,.. (which is stupid) removing TB gives plenty of room to work.

how are you getting the plug wires pulled off thru the intake runners?...
and back on?
every way I've done it, removing the TB has been the easiest. to remove and install.
I recommend cleaning throttle body and ICV while, "3 birds 1 stone"

The old as well as the new plug wires have "pull" handels made on them for the plugs on the driver's side and it made it really easy to remove them. Belive it or not I've seen where the plug wires with the handles were installed on the wrong side the passenger's side.

----------

Right now I''m having a problem removing the EGR valve, damn thing is cooked on at the 27mm EGR tube fitting at the EGR. Thinking to loosen the two 10mm bolts that mount the EGR to the upper intake, maybe a bind?? Dunno.............

right, lol...
my pull handles, had a few different brand set, are not long enough to get to? I cant get to the with hands or tools, hence removing TB. I thought I cld get a boxed end wrench on the hook of the pull handle. no room!.. thought maybe you devised a special tool. or knew something I didnt..

wld be sweet if you cld make a video for FRF users..

No, just loosen the plugs and slip the 3/8" tubing over them to remove and install, then tighten with the plug socket. simple and straight forward. And yes, cleaning the TB and ICV is important, It's the first time for the EGR.

Thinking of up grading the Fuel injectors from 15psi/hr single port to 17psi/hr muti port so I need to at least got the EGR squared away........

Negitive, Just need to R&R the EGR to inspect, Clean / Replace. Then when I do the Injector up grade I won't have to fight with it then becuase I'll have to R&R the upper intake body to get at all the injectors. That's going to be a pain, but worth it.

I do belive they are orange, Can't remember the color code for all the injector psi/hr. Are yours muti or sigle port, stock are sigle port........

Just got on line and orange are suppose to be 19lbs/hr

one side actually starts the enginge then the icm switches the 2nd coil pack to fire the other side after the engine starts. Now, on my 91 2.3 the engine was cutting out spitting and caughing during up-shifting. after replacing the plugs on the exhaust side the problem stopped. Of course afterwards i replace the other four along with a new wire set.

That's one I haven't heard, what's your source on this info?

What gave you the idea that a 2001 2.3 Duratec engine would have more than 4 plugs?

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

Old thread but I completely forgot which OEM plugs I used when I changed them years ago.

It's time again to change them.

For a 2001 2.3L I believe MOTORCRAFT SP-439 are the correct plugs? Can anyone confirm this?

Thanks,
-Nigel
