It all started with high idling revs. I recall seeing on YouTube as any modern respectable self-taught wannabe mechanic does informs themselves. I saw someone say that cleaning your Mass Air flow Sensor sometimes does the trick on fixing it.<\/p>\n

First thing I do is connect my BLCKTEC Diagnostic Tool<\/a> (I bought it at $28.99 August 2023) and see what magical engine codes this produces. P0301<\/a> is what I get. Along with a brief description: "Cylinder 1 Misfire Detected DTC Severity 2 of 3: This fault may pose damage to components and should be repaired as soon as possible". Great! Cylinder 1 is where the first of four spark plugs is located.<\/p>\n

I start by checking the MAF sensor and it was a little bit dirty but not much to really be causing any issues. I had previously purchased Mass Air Flow Sensor Cleaner<\/a> ($12.49) to do this task but waited until today! The high idling revs is still doing its thing. I clear the engine codes on the diagnostic tool. Rerun and same response.<\/p>\n

Next, replace the spark plugs<\/a> (4 @ 6.49 each, $27.95). I also bought some Dielectric Grease<\/a> ($1.99) and two little ketchup size packets of Anti Seize<\/a> ($1.99 each, $3.98). Yes, I did indeed need to replace them either way. This did nothing to fix the high idling revs. When I went to buy the new spark plugs at O'Reilly's I was talking to the employee who was ringing me up for the spark plugs and he mentioned I should try switching the ignition coils that connects to the spark plugs. It was a great idea that I obviously didn't think about. So after replacing the spark plugs I once again clear the engine codes on the diagnostic tool and rerun it. Same response. But now I do what the O'Reilly employee advised, I change the ignition coil 2 to cylinder 1 and ignition coil 1 to cylinder 2. Clear engine codes on diagnostic tool and rerun it and guess what!? "No DTCs", no diagnostic tool codes detected!<\/p>\n

That fixed that but not the high idling revs unfortunately. So what to do next? Messaged my older brothers and Freddy (he's an actually good self-taught mechanic) mentioned clean the throttle body. I head back to O'Reilly's and buy a throttle body & intake cleaner<\/a>, $9.99 bucks. I'll be doing this tomorrow since the engine is pretty hot.<\/p>\n

In total excluding the diagnostic tool since that was bought previously, I've spent so far: $56.40 + sales tax, $4.28 = $60.68.<\/p>\n", "date_published": "Wed, 21 Feb 2024 22:12:00 +0000", "tags": "xb, xb-maintenance" }, { "id": "https://www.czepeda.com/posts/xb-maintenance-air-filter-replacement", "url": "https://www.czepeda.com/posts/xb-maintenance-air-filter-replacement", "title": "XB - Maintenance: Air Filter Replacement", "content_html": "
