What have you done to the car's emissions system?
I get that occasionally as well. Usually just goes away.
Do you have an aftermarket downpipe?
Take your shop to a dealer. Emissions warranty will apply.It's stock currently
My idle blips a little somtimes. It can drop a few rpm, or rev a few rpm depending on it's mood.
I have also been getting a TON of backfire lately. Which is fine with me
So, what you're saying is that this is something that will be replaced/fixed for free by the dealer because of some emissions warranty/law or some crap?Take your shop to a dealer. Emissions warranty will apply.
Or, get the actual VIDA codes which provide you with more details of the actually issue (upper limit, permanent fault, etc). Your generic codes are useless.
I will check all hoses.I was getting the opposite message a few weeks ago: system too lean at idle speeds - Bank 1. Turns out when it took it to the dealer, it was a long term fuel trim code. When they troubleshooted it, they found some hose or something under the intake had come loose. Problem solved. YMMV
Spark plugs and cats aren't really that expensive for me. It won't harm anything else... I've got a spare stock cat, and an aftermarket 3" that I can use which is pretty cheap. Spark plugs are dirt cheap lolA loose/cracked vacuum hose will cause a system too lean code. System too rich is usually a bit more complicated - that means that the car is reading too little oxygen in the exhaust stream and is trying to lean out the mixture to compensate.
And backfiring is bad on your catalytic converter - it means that unburned fuel is making it's way through the exhaust and when it hits the atmosphere, it ignites. Unburnt fuel will ruin a (very expensive) catalytic converter.
You might have an injector that isn't closing all the way and leaking fuel - the fuel gets pushed out during the exhaust cycle and could be causing the backfire. That or a spark plug is fouling up and not burning the entire mixture. I'd get this serviced quickly as you could be damaging critical engine components.
