Throttle return spring mystery solved.

Okay, here's the deal:

Talked to a parts guy this afternoon.  He is smart.  He told me that
assembly line streamlining from 2005 on mandated that the offensive
primary throttle return spring be eliminated.  Sort of.

In the 05/06 TJ's, there are two springs: one in the throttle body, one
on the automatic transmission linkage.  For those of us with 6-sp.
transmissions, well, we get to suck it up and do without.  As he
stated, "You're tough: you can take it."

Well, I'm tough, but I can't take it.  I paid serious bucks for this
horse, and I want all of the springs I'm entitled to!  So, today, I
made a pilgramage to the local OSH for a look-see, and ended up filling
the gap quite nicely.  My throttle response now works as expected.

More information is available at:

Check Hidalgo's Private Garage for the information you seek.  If this
was DC's idea of cost-cutting measures, I am not amused.

    Now you may take your car on to a drag strip, like the Real Jeeps:

Real Jeeps - like the ones manufactured by Ford? :)
L.W.(Bill) Hughes III - 30 Mar 2006 05:34 GMT
    Yes, if built to the same Bantam specs, as Willys Overland:

Are they required on vehicles with throttle bodies?

It isn't like the old days when a broken spring would result in an over
revved motor.....throttle bodies have no control over the fuel supply.

Hi Bill,
    Well your electronic injection would quit with ignition shut off,
but I don't think they would change the rules, we see all stock most
throttle valves, like you see three hooked to my Thunderbird:
http://www.billhughes.com/temp/realCables.jpg It's just Daimler that
f**ked up and probably only on their Wrangler. You'd be surprised at how
many let themselves be pull through the garage wall, or think you must
put it in park and lock the wheel as they traveling down the freeway
before they may turn off the engine. I believe Daimler has left
themselves wide open to every suit that may possibly be blamed to a
stuck throttle.
    And if you were one of the guys that wanted to go fast, you'd
choose mechanical injection, like the Real trucks, and that would
require a fuel shut off:

I thought that double throttle return springs were a federally mandated
safety measure.  I must admit that I haven't thought much about it though.

Someone in the big 3 probably paid off Teddy or Hilary to get the rule
changed if there was one.

More likely DeLay or Santorum.

Here is what I did today to install my missing throttle spring.

http://www.tmar.net/throttle_spring.htm

I drove it for about 15 minutes after the install, and it does seem to have
a much better throttle feel now.

$3.64 eh?  The local Stealership wanted almost $7 for one.  Big
difference after one of these are installed.  Easing it over bumps at
low speed used to be really tough to do gracefully, but no more.

I've got a neighbor with a PT Cruiser that's thinking about doing the
same thing; the primary spring does not exist on that either.
Earle Horton - 31 Mar 2006 00:38 GMT
Just don't put too much of a spring on the throttle.  I knew someone who put
a big heavy spring on his van, to simulate the feel of a tractor trailer or
something.  He wound up with a snapped off throttle cable.

Anytime you need OEM Jeep parts check out the prices here:

http://www.chryslerpartsdirect.com/

If you print out their parts price and take it to your local dealer, they
might match the price, or at least come close.

Thanks, Tom.  The local stealership won't even come close; the last
time I took in a comparison quote, they basically told me to leave and
never return.  Nice people!

I'll give this outfit a shot; Beats outrageous Stealership prices AND
paying state sales taxes as well.  By the time everyone gets done
picking your pockets, you've paid 3X what the darned stuff was really
worth.

http://www.chryslerpartsdirect.com/ is a company I've dealt with
many many times.  They are actually a dealership.  They just don't
try to rip folks off.  What's great is they will work with you
to find oddball parts.

I just wish I lived within driving distance, they would get all my
business.

Might want to back those nuts off and put on
some red threadlocker.  That will help keep them from
rattling off.

A old-timer trick is to slightly press the nuts in a vice to
take them out of round and give them more grip.

Good suggestion Doug.

Hey, I noticed your writeup on the 'fog light mod' - well done, thanks
for the information.  I think I'll attack that offending #1 pin with a
Dremel.  If it works, I'll be sure to give you credit.

I wouldn't mind documenting the deletion of the clutch starter
interlock, but I don't have the parts anymore.  They somehow ended up
under the left-rear tire as I backed out one day.  Then I pulled
forward, then backed over it once again.  Ooops!

Ahh. your throttle arm had no flange on which to fit the clip end of the
spring. Mine did, go figure.
