Jb4 o2 sensor?

[SIMONGUEY]

So I’ve had a jb4 for almost a year now. Bought it off from someone so I def think it’s a old model. Installed some ewg wires that aren’t exactly working which ain’t no bug deal for me right now. But one of my O2 sensors isn’t working properly. One of them is fine the other gets some crazy readings. I have contacted motor sports and have been told it’s loose which I’m sure it is or broken. I’ve tried many different things and haven’t used my jb4 for about two months now I believe. At this point I want to just get new sensors. Anyone know if they have a part number? I’d I can just order new ones or something? If not then maybe the name of the tool to remove the ewg wires safely so I can then buy a new jb4 instead of having those cables just go to waste?

I think you can send your JB4 into Burger for an update/ tune- up. I recall reading that older model JB4’s need something before EWG install. Don’t quote me on that, but check into it.

I'd have to see a JB4 log and install photos for any tuning advice on it.

I've already sent some in. everything looked good. on logs all you said was that my o2 sensor wasn't connected right. after that I left it alone for a while because of work. the main concern would be the o2 sensor first. that's what always gets brought up first before the EWG wires. I have an oil catch can right above the connectors where the o2 sensors have that red connector so I'm not 1005 sure if any oil has spilled into that or not but did have a small leak now too long ago.

that would be pretty cool if so! I miss the gains from the jb4 lol! haven't installed mine again for a while now.

You mean the JB4 fuel control wire? That attaches to the factory o2 sensor per the guide. It's not likely your o2 sensor is bad or the car wouldn't run well factory. Maybe you mean a 3rd party fuel control wire PNP adapter?

my bad mixed it up a bit! you're correct I meant the fuel wires. ill try getting a log today or tomorrow with full install photos of the jb4 all hooked up.
