4.0 running weak
I installed a 700 R4 At in place of my original 5 speed in a 2000 Wrangler.
Short story is that the engine performs very poorly. I need to find someone who
understands the engine besides just hooking up a code reader. Anyone out
there??

Re: 4.0 running weak
Out there where? Describe your problem in further detail. When did it start
acting up. what exactly does it do?

Re: 4.0 running weak
The CPS (Advance Adapters) is mounted on the front of the engine. It is
positioned per AA instructions. I took the rig to a hot rod shop in Phoenix.
4 hours of tweaking and trying different settings only produced worse results.
The diagnostic reader showed the timing to be "off" but setting it to spec.
caused the engine to run much worse. One of their last exercises was to
install a pressure guage on the exhaust pipe ahead of the cat. conv. it showed
approx. 5=6 lb. of back pressure at 4k rpm. Then they said I must have an
obstruction in the exhaust line as I should show no more than 2-3 lb of back
pressure and that must be the cause of the problem.
So I went home, took the cat. conv. off and replace it with t straight pipe.
The cat showed no apparent problem. The car runs just the same. The exhaust
muffller is a Borla and I have not disturbed it.
The engine runs smoothly with no missing. When "stepping on it" at moderate
RPM's it just "wilts", acting like it is getting too much or not enough gas. I
will add that I have an Avenger supercharger installed but I believe my
problems are not associated with that.
Thank you for your feedback.
