90 Jeep Cherokee 4X4

any one have any ideas what i need to do.


about? :dunno:

For starters the 90 uses a completely different fuel-injection system than the 93 does...also the 90 lacks an onboard diagnostic system of any kind, whereas the 93 has one.

Youll either have to get a donor vehicle with the same setup as the 93 and start swapping a bunch of stuff over..or count your losses and get the right engine to start with.

You would need an engine from an 87-90 Cherokee.
