Sluggish as hell on take off, 96 zj

[HeavyMetal]

My mothers 96 ZJ, has a 5.2 and an auto in it.

Right now it is super sluggish on take off. the throttle response is there, aka i can mash the pedal and the engine will respond right away...but its reallly sluggish. i mash it and it slowly accelerates up to speed compared to what it normally does. when im cruising at say 30+, i can work the pedal on and off and all feels totally normal, but slow speeds and from a stop its very apparent. she said it is definitely worse in the cold weather. this was all test at operating temp as well...as well as cold running.

maybe a clogged up airfilter? maybe something with tranny fluid? maybe throttle body?

whats everyones opinions? lemme know if i missed any info that needs touching on

could be any number of things

first off is the cel on?

second off

when my 96 xj was shitty and sluggish this summer, it was the fuel pump.pressure was about 10 psi below spec.

but check the easy things first

CEL is not on

ill check pressure visually, best i can do right now, prob wouldnt notice a 10 PSI change though.

Might not be down shifting into 1st my tranny used to do that changed shift solenoids and bam it was good.

To test it manually shift it

possible torque converter issue?

might be slipping at idol/low rpms, but that would correlate to high rpm's with only a fraction of the true movement speed, it sounds like what your describing is more a fuel issue

that reminds me of a good way to explain this

it feels like when youre in a manual tranny car and you take off in the wrong gear and it is super slow to get up to speed as a result

it isnt choppy or bogging down or being uneven at all

check the kickdown/tv cable adjustment

if it loosens up it will cause the jeep to be stuck in a higher gear

and it takes about 4 seconds to adjust

sounds like a tranny issue to me, especially since its a ZJ. i'd put my money there unfortunately.
