Moved and now my jeep pings...
 

Question for you all, I Bought my TJ in CA back in 01'. Back in Dec I
moved to Texas, and notice my jeep now pings under load when I put in
my normal reg. Gas (87 oct). This is the same gas I have used for the
entire life of the jeep.. so now I tried to put in mid grade (89 oct)
and it works just fine. Anyone have any ideas? Is there anything
that is on the TJ for CA Emissions that I might be able to tweak or
take off now that I am in Texas?

TIA
Kurt

Re: Moved and now my jeep pings...
 

You have already fixed the problem. There are fuel quality and additive
differences from state to state or region to region. There isn't anything
that you can adjust, but if everything on TJ is working correctly, it will
eventually learn to run on the cheaper gas.

I wouldn't do that. If you can hear the ping, imagine taking a hammer and
whacking the tops of your pistons on each upstroke. That is what ping is
doing, and no good comes from it.

Bottom line: if TJ likes mid-grade, feed her mid-grade.

Re: Moved and now my jeep pings...
 

Are you at a differerent altitude?

Are you buying the same brand gas?

Check with your brand gasoline to find the additives it uses in each state.

What part of Texas? Some parts sell 86 octane rather than 87 AIR. I
think some parts also use the oxygenated fuel (seems to me I saw that
in Dallas/FW last time I was down there in December) but There I'm not
sure. I know my old 88 4.0 sure does dislike the oxygenated crap.
You might also try a different brand or station for your gas.

Or it might be something as simple as blowing the carbon out - a 50
mile run dow I20 at 70-80 mph should do it (or a can of water thru the
intake - SLOWLY!

Thank you for the reply, When you say "blowing the carbon out" what do
you mean? I am in Austin now, I did notice some places have 86. but I
am pretty sure we have 87 here in town... Also, in CA they used
Oxygenated fuel (if i remember right, they also have MTBE) and now
that I am in Austin, i dont think any of those are in there...

But its more expensive and I'm a tight wad! :) j/k.. actually in the
TJ manual it actually states NOT to use Midgrade or anything higher
then 87... So i was concerned...

Re: Moved and now my jeep pings...
 

Thank you for the replys!
At first i figured it was a brand problem so I have tried Exxon, Chev.
Valero and Diamond Shamrock (which are one and the same) and those
are what I use to get in Ca.. Also, i am at 900 ft elev here in Texas
and in CA I was at about 300 ft.. so not much of an elev difference...

Re: Moved and now my jeep pings...
 

The midgrade fuels or premium fuels won't damage anything. They just cost
more. Also, you may want to try a different gas station. Avoid the Holiday,
Clark and C-store type places, as their gas is sometimes not as good, even
though the octane rating is the same. Also , decarboning the engine like
someone else mentioned, may cure your problem.

The easiest way is to just run it up I35 to Temple and back. I'm just
thinking that if you haven't had it out on the road at sustained high
speed and full temp for a while the cylinders will load up.

The other way is to run about a quart of water (some suggest ATF, but
that makes a smoke cloud you have to see to believe) and run it thru
the intake. Get the engine up to temp, pull the air intake hose off
and SLOWLY dribble the water in. Keep hold of the accelerator pully
to keep it from dying, but don't go wild. You don't want it to go in
fast enough to hydrolock the engine. Some say to use a good spray
bottle and spray it just fast enough to make the engine stumble a
little. That will scour any carbon out of the chamber that could be
causing pre-igniton. I have a little trouble with my MJ when I get
down there but I think most of that is the CPS I have - the dealer in
Colorado only kept the high altitude version which advances the timing
by what looks to be about 5 degrees or so. Texaco gas is also pretty
good, but I avoid Fina most places in Texas other than near the
refinery.

Re: Moved and now my jeep pings...
 

the emissions and the fuel injection requirements are way different from
ca. to texas so much so that the soft ware is labeled fed. emissions and
ca. emissions so there is a good chance the pcm should be reprogamed to
cure the issue. and if you are in good terms with the local dealer and ask
for help nicely they might do so under emissions warranty

Part of the problem could be the very recent downward drastic
movement in what passes for quality in gasoline brews. All the
oil companies out here [Kalifornia] claim that the new ethanol
blends are superior yada yada yada. A couple also claim that
adding minor amounts of ethanol to gasoline stock will improve
the octane rating by a few points. Perhaps I've become too
cynical but to me that tells me that they are now using even
crappier base stocks with the ethanol, as there is no monetary
advantage for them to exceed the pump rating.

With a 4.0 I have always had an extremely light ping in town,
typically at transmission shift points. Easily gotten rid of
by moving up from 87 to 89 or just buying the 87 gas in Nevada
or Oregon rather than California.

Since the new ethanol blends have infested the local gas stations,
this no longer works. I get moderate ping under city traffic
conditions and it will only go away if I use 89 rather than
87. Haven't had a chance to try Nevada grade 87 yet.

Blowing the carbon out is generally done with an "Italian Tune-up"
named after old Alfa and similar engines that really did not like
being trundled around in town. Take the vehicle out of town and
floorboard it up thru the gears a few times.
