The first year fuel injection was in the Wrangler form the factory was 1991 for the 4.oL. The 4 cylinder initially was a throttle body then multiport later, but I do nto remember what years those happened. When I was looking for the one I have now, the blogs about carb problems is what prompted me to determine 1991 was the oldest I would buy. I did used & still have it 10 years later.
