Re: 4.0 vs 4.0HO?
 

Why would you want to do that if the engine you have is o.k? I replaced the
screwed '91 HO engine in my YJ last year with a '89 LO engine from a damaged
XJ. I did that because the HO engine is very rare on junk yards here in
Europe. The difference in preformance is like not there. The swap took me a
weekend and I would do it again any time.

If you say so.... My 88 has turned 300K km and runs great.

Well there you go, you have 'really' nailed the difference in my
thinking vs yours!

The big difference is that pesky one hour labor to look at anything!
Here in Ontario Canada it is $79.00 or $86.00 plus 15% tax! A Cool
hundred bucks!

You are 'forced' to pay this to reset a stupid timer that is an instant
'Fail' on an emissions test.

I mean seriously, how many folks feel competent enough to remove a
freaking dash board to pull that bulb?

That is a 'major' job if you have never done it before.

Yup, I have issues with stupid crap like that!

No, I just have seen the new ones post their mileage here and I have had
them come on 10 day trips with me and we compare fill ups at the same
time....

Not scientific, but a 'real life' test on 'many' occasions over the last
5 years.

I am always lower for gas used volume in my Cherokee 4.0.

Then if I am in my CJ7 comparing it to the TJ 4.0, well they just can't
believe it. I get radically better mileage running off road logging
road trails, 10 liters difference in 200 km usually, let alone my sweet
19 US mpg or 11L/100km Canadian on the highway. I get a nice 24 US mpg
in my Cherokee running empty. Fully loaded with 4 adults and camping
gear, it goes down to 20 mpg or so.

There are a mess of folks from this newsgroup that can confirm this
because they were the folks I was comparing to. It is no BS, bllsht.

I'm sure it does. I wasn't saying they run bad, just that the Chrysler
controlled ones run better. Although as far as annoying repeating problems, the
Renix system has many more.

Can't speak on emissions testing anywhere but California, but an illuminated
emissions maintenance reminder isn't cause for a failure. There isn't even a
functional test for it in the inspection procedure.

Anyone who considers removing four screws in plain sight a 'major' job,
shouldn't be complaining about having to pay to have it done. It's not exactly
rocket science.

If you say so. The problem is you could drop 5 mpg just by changing drivers.

Anyone who considers removing four screws in plain sight a 'major' job,
shouldn't be complaining about having to pay to have it done. It's not exactly

Too many variables involved to consider taking your claim seriously.

If you say so. The problem is you could drop 5 mpg just by changing drivers.

I'm sure it does. I wasn't saying they run bad, just that the Chrysler
controlled ones run better. Although as far as annoying repeating problems, the
Renix system has many more.

Tax on labor? You guys still trying to figure out how to pay for that free

Can't speak on emissions testing anywhere but California, but an illuminated
emissions maintenance reminder isn't cause for a failure. There isn't even a
functional test for it in the inspection procedure.
