According To Honda: None of this fixed my p0300

Jeph629: I had a misfire--but ONLY ON HARD ACCELERATION in my '99 M3-- after replacing 6 ignition/spark coils and 6 plugs ($$$) still no fix! A mechanic spent a lot of time---found the coil boots were old and cracked rubber with the spark shorting into the engine block. These folks sell just the boot: https://www.youtube.com/watch?v=gu6yzbIYnsQ (BTW, god-only-knows why the BMW dealer charged me $1200 and did not replace the boots with the coils to begin with.......?!)

Ahmad Hamza Balad: Couldn't it also be bad ignition coils?

Carly Corrar: My AC blower stopped working and then this happened and it won't start. Any advice?

Alex Jansson: I had these issues on my 2010 Hyundai Accent and 2010 Acura TSX. For the Hyundai it was bad ignition coils. For the Acura it was loose ground wires from somewhere around the engine. Both issues were electrical. Spark plugs rarely go bad now a days.

Jason Green: I love whaching your shows there so helpful went iam stumped on where to think to checkout next for problem and iam not mechanic but it shore saved bunch time and money thank for makeing videos

Dott 5: No he didn't jump out the back of the truck like a knock lol fuccckk!

Hamed Adefuwa: Ive been watching all ur new videos but this old one just helped me out loads

Wrenchettes: thanks scotty just got this one today :(

Daniel Madden: Good video is there anything else, here is my review 1. Spark plugs 2. Coils ? 3. Vacuum leaks 4. Battery 5. Throttle body ? 6.fuel pressure. 7.

82guerrero: Awesome thank you for the video. Lots of help

Jayjay42023: So what if your check engine light is blinking on and off and it feels like you have multiple misfires and they replace all the ignition coils and spark plugs this is for a 05 Nissan Maxima could High have purchased the wrong spark plugs if so what happens if I purchase the wrong spark plugs

Michael Rivera: Awesome Video. Just bought a 2007 Dodge Magnum with P0300 Code and P0660 codes so this video was helpful. Thanks

Steven Criscione: wow, I forgot all about the intake spray test... And to think I used to do it back in 2009 LOL... Right now I have a problem with my GMC Jimmy and every test has been done and everything has been replaced except for the Spider injector... And I have multiple misfire but one of the cylinders misfire is more than the others... my mechanic took a look at it and says that it could be the Spider injector, but what if he replaced that and then ran into an actual internal engine issue?... Sucks

Brandon Parks: This video just saved me hundreds of dollars. my car was having a misfire and so i replaced optispark, wires, and plugs. And it still had a misfire. Watched this video and went down to my auto parts store and had my battery checked and they said it was bad. I put in a new battery and now no more misfires!

MrRuben4581: Lol I like this guy

427 Elevating Productions: Thats something older people disagree with me on. I have tried over and over to explain to them just cause a battery starts your car does not mean you have a good battery. You battery can start your car okay but, say for example one battery is rated at 650 cold cranking amps and you have a test run on it and the rating comes in probably at 490 or 500 cold cranking amps most likely a tester would deem that as a bad battery or one that is probably getting weak. Glad to see a mechanic who also confirms what I know. Especailly one who has been a mechanic practically his whole life such as Scotty

K Santana - Official: Mine has a random misfire code i fixed spark plugs i fixed pcv valve & changed lean , it still dies can somebody help ?

cw sx: The end in the truck lol 😂 Gotta love Scotty!
