Re: Fuel Injection

The first year for fuel injection in a YJ was 1991.

The system was very reliable in the YJ from that date. It has been in the XJ's for a few years prior... and the bugs were worked out.

Re: Fuel Injection

I thought '91 was the first year for fuel injection on the four litre, but that the 2.5 got it earlier. Am I mistaken?

Looked it up. http://www.off-road.com/jeep/tech/engine/amc150.html says the 2.5 had throttle body fuel injection from '87-'90, and after that multi-port fuel injection. Anyone wanna explain the difference?

Re: Fuel Injection

91 was the first year in the 6 cylinder. I think the 4 had it earlier though.
