TBI?  Anything past 1991 will have MPFI and not TBI.

Best pic I have of it when it was TBI


This was a couple years ago after I lost the oil cap on a trail.

Wait, that's from your MJ.

I'm still wondering about this TJ with a TBI.

He is wondering if there is a larger tb available for TBI. The answer is no unless you bore one out like sharp did for me. Worked great on mine but requires machine work.

Well, the OP is asking that but Hunter seems to be saying his TJ has TBI.

Hunter's old and doesn't know how. BUT, Hunter's going to have his 12-freakin'-year-old grandson show him how this weekend.
