My 98 xj started this neat trick. it thinks it's carburated . i have to hold my foot on the gas to keep it alive for a second but only if it is under 40 degrees outside and it's been sitting.otherise she runs sweet. no check engine light plugged into it say's everythings a go..i don't wanna throw parts at it i know it could be a bunch of things. anyone had this issue with theirs?

 

I have this with my 92, but more extreme cold. 2 days ago it was 3 out when I was trying to leave. finally got it to kick over by giving it a bunch of gas while it was trying to turnover.
