I have had code P0456 & P0442. I have replaced the gas cap(OEM), purge valve (under the hood) & EGR valve. Still getting the same codes and car feel like it is rough idling about to stall at a dead stop. I have located the charcoal canister. Do you think that may be the problem? I do notice a gas smell.

Could this be why my car accelerates without even hitting the gas pedal from a stop and gets up to 50 mph before I brake

Does the check engine light have to b on for it to b the spark plugs ?

Might be the problem with mine even though I went to a shop for repairs and was told that everything was good that I just needed rotors 🫠🫠🫠

Spot on my man, i would only add speed density engines (map but no maf) react the opisite to vacum leaks. The engine runs higher rpm than normal beecause the computer adjusts for the pirate air. Maf and a map both on the engine they respond just like a maf, low idle and want to stall

Have any ideas what cylinder p0300 is

I have a car scanner through obd2 port (Hyundai i30 2008) and i see that the throttle position range in % is between 6,67% (on idle) and up to 33% at 6000rpm (the maximum i have tried so far). Could such fact be a throttle position senor issue? I have already cleaned the throttle body! Thank you very much!

I've similar symptoms, ive changed the BMC but it didn't work. Sometimes my break works sometimes not. I also hear a noise like air pump when pressing the paddle. My left back wheel is not pulling break oil. Maybe some air trapped inside? Oil doesn't come from one abs valve. What should I do

I have a Mazda 6 2018, and the issue is that the air flow is weak, especially at lower speeds. I can barely feel any hot/cold air coming out. The cabin air filter is new. The blower motor makes no noise, it seems is working fine, as well as the blower motor resistor because it lets me change the speeds . However, I also noticed that the driver’s side vents the air flow is weaker. What could the problem be? Could it be that the AC pressure is low?

My radiator exploded in the in-n-out drive through… I was so embarrassed lol

I’ll be honest, I didn’t understand one fucking word that was said.
