Help on 2015 Jeep Wrangler!
2015 jeep wrangler
Manual transmission
when accelerating through 1st through 3 the motor starts to bog down when under acceleration. went to a local AutoZone and they used their scanner to see the problem and nothing popped up and there's no misfire.
buttt I've had a bad o2 sensor in the jeep for 3 thousand miles and that showed up on the scan but I knew about that, and for those three k miles that have been driven on the jeep it hasn't had a single problem and the jeep has been driving fine

Catalytic converter may be getting clogged. Expensive fix. O2 a massive pain, but can expose some problems between them. My guess is error appeared because of the catalytic converter and over time, it's gotten worse, to the point where it's affecting drivability. Would think it would throw an additional code, but not sure that's always going to happen? O2 may be the code? Just an idea from right field.

How long does it bog down for? I have a 2012 manual trans. I had a momentary hiccup in engine power. It doesn't sound like that's what you are describing. Mine was fixed with a new crank position sensor. I never got codes when it had the hiccup.

Maybe some other things to look at is loose or disconnected vac lines. Sounds like a fuel to air mixture problem, which cld be some faulty sensors that are working but not within there perimeters (therefore not causing eng code) or extra air getting in. Does the big clean up after a certain throttle position or rpm?? Cat is a little too new to be bad, but we dont know what kind of wheelin or elements it's been thru either.. lol..

will be ordering a new o2 for the cats and seeing if thats the problem if not im going to take a look at the crankshaft sensor and see if that fixes it
