2004 Grand Cherokee (set up for expeditions)
After last year's "Steve's 4x4's Great Adventures Rallye".
After 724 miles of On Road / Off Road driving,
I found several items that needed attention.
But one still was a reoccurring problem. It appears after running for a Good while on the road, it would loose power climbing a grade. If you went to WOT, it would stumble, and if you Let Off to say 3/4 throttle, it would get a little better.
It would act up quicker and worse if the Ambient Temperature was above 80°.
Thinking it was Vapor Lock happening as that Carb is right there above the Exhaust Manifold, and boiling the gas in the carb. I bought and installed a "Heat Shield Plate".
Not as bad, but the problem was still there.
So, I bought a Master Carb Rebuild Kit.
Today, I braved 15°F in the lower barn, and removed the Carb, and Heat Shield Plate.
TaDa !! On the bottom of the Heat Shield Plate is a WITNESS MARK of Black Carbon ever so small, but Ray Charles could have seen it !!
There is a Exhaust Manifold leak coming up on the back side of the Intake Manifold going right at the Carb Base.
If I didn't buy that Heat Shield Plate, I might be still looking for the problem.
Now besides rebuilding the carburetor, it is only more Entertainment to remove a 75 year old Intake and Exhaust Manifold!!!
Ordered the Gaskets, a Heat Riser Kit, (the rear shaft bushing was so worn out I jammed a Spent Rifle Casing into the hole to seal off the exhaust blowing onto the firewall), and Brass Exhaust Nuts.
Any Bets on How many Manifold Studs Break Off ??!!
I will post pics of this calamity.
