I love you. Seriously I do. You *actually* tell people what to do and how to fix things (also what not to waste your time on). As a single mother on one (LIMITED) income and "intermediate" knowledge of auto mechanics...you help me tremendously!! THANK YOU!!!!

[wearetab]

WOW. Skip the chatter, right to the point! I like your style. Others would have needed 25 minutes to explain that.

Hello Scotty, last weekend i had a warning ( check engine ) . I checked my engine with the ODBII and had a code P0300. I replaced all 4 sparkplugs and now my engine works great and have no warning signs. I did another check with my ODBII and have no faultcodes.
With the help of your video i saved a lot of money and my engine ofcourse. I made also a testdrive and everything is smooth...So Scotty thank you for your great tutorials. Gr.Marc from Belgium.

Hey Scotty, I just used the switching the coil method for my Mercedes C300. It worked perfectly because the problem did move to the other cylinder. Thank you for the knowledge you pass along.

Scotty I love your videos. I wish I could find a mechanic even close to you. My mom has been robbed by the stealership for fixes that cost half the cars so I appreciate you giving me the knowledge to try and help my family out on a very limited income.

Learned so much more than just the spark plugs and ignition. Now I know when the engine is worn out and should just be replaced or trashed and shouldn’t put all that effort into an engine rebuild. Thank you Scotty!

Thank you Scotty. Ive been working on my Mother In-Laws car today, a 2011 Chevrolet HHR. You just help me figure out what's wrong. I watch your channel religiously!!!

Scotty is the grandfather of mechanics! I’ve been getting help from him since I got my first vehicle 10 years ago

Scotty, when I see these videos I appreciate even more my Honda and Toyota..

[jaydavis]

If I had a shot for every time Scotty said "flat worn out" I'd be flat worn out

[northstar]

I hate that P0301 code....with a passion...

[franciscotarelo]

Your channel is without a doubt one of the very best.
Keep it up Scotty 😊

Fixed my Mazda CX5 with a Battery and spark plugs swap. Thanks Scotty!, 2015 226, 000 and still starts right up and runs smooth

If the Audi was pre-2009, it's most likely carbon build up. The FSI engine is the most carbon build up prone engine ever.  It was VW/Audi's first turbo 4 with DI. The engine wouldn't be wearing out, those are solid engines. But as you said, it did lose quite a bit of compression.

Hi Scotty. This video helps me a lot, I mean, after all research on YouTube and internet, I came to conclusion that my Nissan Pathfinder 1999 with more then 212 k miles on it, actually getting to the end. The last step left for me to check is compression test. I did almost everything to fix missfire on cylinder nomber 3 with code PO303 and also PO300 as wll which is one of the worst codes one can get. ? Spent good amount of money to replace O2 sensor, EGR valve, spark plugs, wires, brand new fuel enjector for no, 3 ., also I replaced both valve cover gaskets which is pain in a butt expecially driver side undr the plenum. . I've had some confidens in myself and I beleived if I do all that I may fix it, . After all that I did test the car and nothing has changed. The car still shaking when on stop and cant drive up hill more then 35- 40 mph. So I will do compression test and if it's too low, I will sell to junk yard.

I really like your videos. I bet you'd be fun to drink a few beers with lol. I rarely need any advice with auto repair, though I have learned a few tricks from you that I just never had thought about before. I just like to watch your videos. Keep up the good work!
