The two most common reasons I have found in my experience you left out. Number 1 I have seen most of is stuck open purge control valve. And also worn out spark plugs not burning all the fuel. I have also seen cars with both a map sensor and a mass airflow, I’m pretty sure. I can’t remember what car that was on.
Thank you, Your Knowledge of Automobiles, and components is amazing hope you are a millionaire, and thanks for your videos, finally a person that is very smart! and Honest...
Very helpful thank you, I've had this problem with a Seat Ibiza, I ended up replacing the fuel filter and fuel pump because of idle issues, but I believe it's the oxygen sensor (lambda sensor) that is causing the the running rich issue. Those oxygen sensors aren't cheap!
been having rough starts on my Dacia Sandero and incorrect coolant temp reading ... i've read almost everywhere that it is a bad thermostat but decided to change coolant temp sensor anyway ... spent 3€ on the new sensor and now the car starts like new
Hi, I enjoy your videos they are very good. I have a 2019 Ford Transit 350 2 litre diesel UK model (I live in the UK) I have a single radiator fan with 2 speeds; High Speed and Low Speed. When I turn my AC on, my Van no longer uses the Low Speed fan, it ONLY uses the high speed fan in 30 second cycles, and then turn off, and then again repeats the cycles. My van never use to use the High speed Fan when using the AC; it would only use low speed van. My van is not overheating at all, nor does the AC NOT work; it blows freezing cold air, as it always did, and there is no engine performance issue. I have gone to 3 different mechanics and they have all used their fancy scan tools, and they cannot find ANY fault codes on my van or see any abnormal values, when testing on Live View. How do I go about resolving this issue ? Have you got any tips for me on this issue, or direction for what I can do next ? please do let me know Thank youuu !
Hi! I have -128mA b1s1(upstream o2)and 10 kpa intake manifold absolute pressure, and it´s stuck at these values. Anyone have any idea of what is at fault?

Hey bub, I have a yr 2000 Accord ulev-4 and I changed my spark plugs and now I'm getting nothing but static from my radio, I looked for any Ground wire by the battery and nothing, what happened bro.
Hello Bob, I have a 2009 Corolla the check engine light came on and shows a p0013 code I tried swapping the cam actuator but the code still remains. Please what may be the cause. Thanks
@@Top5AutoRepairsYAY!!!🥳🎈🎉♥️ I just found your channel. Please Sir...desperately need help. My 2008 Kia Optima just started this...not wanting to start after filling up at gas station. It takes several tries. I had Purge Valve replaced, both O2 Sensors replaced, Canister Vent Valve replaced and cleaned Throttle Body. So aggravating. Any suggestions?? Thanks for any help.😊
This guy forgot code p2188 and he also said a car that has a map sensor doesn't have a mass air flow he's wrong a mazdaspeed 3 has a map sensor and a mass air flow
My Honda feels forced, it will gradually go up in speed if I press the gas slowly but say I need to pick up speed quickly and press down on the gas all the way the rpm will shoot up but the engine won’t accelerate. Any tips on where to start? No engine light tho
