Check engine light!
Hello, I've come across a problem. I got the codes P062D, P1235, and P0300. Recently I changed out my spark plugs due to the fact my car unexpectedly was underpowered and my exhaust did not sound as loud. Not only did it not sound as loud my car drove and felt different. So I changed out the sparkplugs not long after, I got a check engine light and I stopped the car and pulled over. I called my uncle to help and right when I started to move my car stalled. I have an automatic version, I know it's not impossible for automatics to stall but still, it was very surprising. The RPM idling was a lot lower than what it was before I changed the spark plugs. I honestly am so lost on what to do.

p1235 is a fuel pump error, the other 2 are misfires.
what mileage is your car, what mods, and what plugs did you use?

My car has 80K miles on it and the spark plugs I used the NGK racing competition and the only car mod I have on it is the MXP rs comps. I bought 2 fuel injectors because I believe I might've done something on the driver's side. And which fuel pump are you talking about? the Front HPFP or the actual gas fuel pump in the back?

um, racing plugs have a whole lot of prerequisites with them. did you read the description before buying?

more than likely, your first step is to re-do what you already did, and install oem replacement plugs that are gapped correctly. https://86speed.com/oem-toyota-spark-plugs that will get you back to the original problem. hopefully. you're throwing parts at a problem that wasn't diagnosed beforehand. you more than likely have even more issues then you started with. all i can tell you is what google says for the fuel pump code.

Iridium-tipped electrodes must be handled with care. They must never be gapped. If a plug ever comes out of this engine needing anything but a nod of appreciation, something else needs attention.

i used to always go to the same place for parts. the 2 guys i knew there would have the vehicle pulled up, just asking for what i needed by the time i reached the counter. i didn't need to remember the trim, or the model year... but then the day came where those guy's weren't there. as the new and obviously non-car-person started asking me for what trim, engine size, etc. i needed a headlight bulb for, i couldn't resist.. "oh yeah, almost forgot! i need to grab a water pump as well!" "it's for a '72 vw beetle"...

Do you know what wire? Did you have the Wire Manual? If you were just randomly hooking up wires hoping for things to work then A) you blew a fuse, so just go through all of them and check. B) you smoked a component.
