So I have a 2019 Toyota Corolla Le and originally the temp dropped 12/23/22 and I had p0171 come up and I had both oxygen sensors replaced then same code plus all 4 cylinder misfire so I changed all spark plugs coil packs and air filter. Then p0171 came back checked maf it was good. Now p0171 plus p0441&p0455 just came up as well. It feels like it wants to cut off when I stop but no problem when I accelerate. When sitting idle the rpm’s jump around between 0 and 1. I’m in desperate need of help since I have already spent 600+ on fixing things that wasn’t the problem. Please help!
