I’ve got a P0430 code (Catalyst System Efficiency Below Threshold) on my 2015 Ford Explorer. Do I really need to replace the catalytic converter, or could something else be causing it? I’ve read online that sometimes it could be the O2 sensors? Trying to avoid a big bill if possible.

Hey guys, I got the P1151 code on my 1999 Ford Ranger (Oxygen Sensor Indicates Lean). The truck’s been running a little rough and I can feel some hesitation. I know it’s probably the O2 sensor, but could it be something else like a vacuum leak or fuel pressure issue? What’s the best way to troubleshoot this before replacing the sensor?

Hey everyone, I’m trying to replace the stereo in my 2010 Ford Taurus, but the wiring color code is confusing me. I’ve got the diagram, but I’m not sure which wire is which. Any tips from someone who’s done this before? Do I need to get a specific harness adapter or can I wire it myself?

I just started getting the P0171 code on my Ford Focus after it began idling rough. It says the engine is running lean, but I have no idea what’s causing it. Any suggestions on where to start looking? Thanks!

I’ve got a 2007 Ford Fusion with a P0443 code – something about the EVAP system. I know it has to do with emissions, but I’m not exactly sure where to start. Does anyone know how to troubleshoot this one? What should I be looking for? I don’t want to start replacing parts if I don’t have to.

My 2012 Ford Escape is throwing a PO171 code – System Too Lean (Bank 1). The car is idling rough, and I’m getting terrible fuel mileage lately. I’ve checked for vacuum leaks and cleaned the MAF sensor, but the code keeps coming back. Could it be something else? Is it worth checking the fuel injectors?

Hey everyone, I’ve got this PO430 code showing up on my Ford F-150. I have no idea what it means exactly, but from what I’ve heard, it might be related to the catalytic converter. Could it be something else causing this? I’m hoping it’s not the cat because, let’s be honest, those things aren’t cheap! Has anyone dealt with this before? Any other things I should check before assuming it’s the converter? Maybe an O2 sensor or some other part?

Hey all, my 2005 Ford Explorer keeps showing a P1131 code (lack of HO2S switch – sensor indicates lean). Engine seems to be running a bit rough too. Anyone else dealt with this? I’m thinking it might be the O2 sensor, but could it be something else? Do I need to replace the sensor or is there something I can do before that? Any help would be awesome!

Hey guys, I got this weird P1000 code on my Ford Mustang GT 2016. The car runs fine, but the code won’t go away. I’ve cleared it, but it just keeps popping up again. I read somewhere it has to do with readiness tests not being complete after a battery reset? Anyone know what’s up or how to fix this? Should I be worried or just ignore it?

Okay, so I’m finally ready to lift my Bronco, but there are so many options. What’s the best lift kit out there? I don’t want to go too crazy, just something practical for off-roading without wrecking my daily drive.
