Misfires due to you being a cheap bastard and not changing your spark plugs
Sometimes that's good, sometimes it's bad. You get an engine light and you scan it and it deletes the code and when you go to the dealership if it doesn't come back you just paid them to say to you that you deleted the code and they can't run a test plan on it to see what's wrong.
Damn, didn't know that. I mostly know about from watching my cousin who's a mechanic and the first thing he'd do on any modern car is pull out the reader and do a scan. (Admittedly he started working way before they were a thing.)
Emissions or sensors are usually the more common issues. If the engine light is red then that can mean something major if it's yellow/amber it could be anything even the gas cap like others mentioned. Be careful with the code readers, don't delete anything or it gives us nothing to go on and in all honesty if you don't know much about cars the codes aren't gonna do you much good. I work in automotive and I can't tell you how many times customers will come in with the code thinking they know what it is based on Google, erase everything and then can't tell you any info like if it's been running rough, any noises you've been hearing etc. Understand that the code readers aren't a magic tool, a lot of people think "Just plug it in and get the codes" like we wave a magic car wand but 99% of the time it will also require proper diagnosis as the codes will give you an idea of what is going on and a general idea of where to look but you normally need to test as well. As for my guess I'm gonna say something emissions related.
That's what mine was last time it was on.
My favorite is when a car comes in and they have a piece of black tape covering the light so they don't have to look at it lol.
Well I know a bit but count yourself lucky you won't do what I did then. My starter motor was on the way out (I'd flooded the engine before hand going through a deep'ish flooded road, needed a total engine replacement, it had sucked water straight into the block, utter fkin nightmare...)
ftfy
No, they really don't.
So a bad canister purge valve like my car? Admittedly it was at a 160k miles before that happened.
No, they really don't.
I miss the days of engine trouble? Ahh, just take out the solenoid, give it a bang. Good as new
Aye, it's a complete joke. I had a few cars in the mid to late 90's, it was so much easier. Even getting parts was a breeze. There was always a breakers yard just down the road if needed
Make sure when you fill up with gas you don't put any additional once it switches off. You can get fuel in that cannister and it needs replacing.
If you were a good boy you would have a garage change the oil as part of a regular service interval
