I have secured the loose skid plate on my pickup ($).
I like easy (read “cheap”) auto repairs. The other two unexpected pickup repairs this year have been:
1) New front wheel bearings while down in FL ($$$)
2) New heater core ($$$$).

Is there anything more frustrating than a P0420 code popping up right after an exhaust upgrade? Spent the afternoon testing this 90-degree O2 spacer with a mini-cat inside. Does the trick for those persistent sensor readings. 🛠️ #o2sensor #diyautorepair o2sensorspacer.com

That constant P0420 code after a high-flow cat upgrade is enough to drive anyone mad. If you're tired of staring at the CEL, a simple 180° spacer with a built-in mini cat is a clean, effective fix. No fuss, just clean logs. #o2sensorspacer #carrestoration #diyautorepair

Finally found a decent O2 sensor socket kit that doesn't feel like it's going to snap mid-job. The offset design is a lifesaver for tight engine bays. If you're doing your own exhaust work, this is a must-have. #mechaniclife #diyautorepair #minicatalytic

Just took 15 minutes to fix the center console lid that bounced up & down while driving our 2011 Sonata. Catch was broken, so I modified a clip nut, drilled through the inside of the compartment, and riveted the hacked part to the latching well. First try!
