    About 3 months ago I had a p302 code. I replaced plugs, wires and #2 injector. After the jeep ran a lot better no problems.
    About a month later I started getting p404 EGR codes.

    now, roughly 3-4 months later I’m getting p302-p202 codes for #2 injector again.

    i am just wondering if anyone has had similar problems? Is the injector codes I’m relation to ongoing EGR problems? Any insight would be great thanks.

    I have a 2010, wrangler,3.8-6cyl. got it last fall, was getting p404 c0ode changed gas cap no more problem. lately I've gotten a p2096, and a po132 code, none of these have hamper performance or gas mileage. Over the months, I've got several other code. Seems like it notorious for logging codes. I got a cheap reader at Walley world. keep it on the glove box. if it doesn't mess with performance, I reset it. It has logged some codes once and never did it any more. so your guess is good as mine.

    Those codes are linked to O2 sensor issues which may not appear to affect performance or mpg but the incorrect air/fuel ratio etc could have long term implications leading to other problems. Check out the O2 sensors from RockAuto for pricing plus 5% off to help with the shipping.
