I just purchased a 95 Wrangler with the 2.5L 4 Cyl. engine. I get a code
21, which is related to the 02 sensor. The guy I got the jeep from just replaced the 02 sensor. The connector was bad, so he cut it out and spliced the wires together and got mixed up. He said ever since then the light comes on. The engine runs fine, but does not idle well when it heats up, I am hoping this is related to the sensor, but it may not be. I just want to get the light out.Can anyone tell me how to wire this thing? There are the following wires coming from the wiring harness:
Black Black with Blue Stripe Black with Green Stripe Green with Orange Stripe
and coming from the sensor: White White Black Gray
This is how it is currently (runs this way): Black - White Black/Blue - White Blk/Green - Gray Green/Orange - Blk
I've played with as many combinations that I can and either the engine will not crank, or I get the same check engine light code. I can go purchase another o2 sensor in case this one is fried, but wanted to try to get it wired right first.
Any help would be greatly appreciated!!
