2005 Nissan Maxima SL
Big fan of your channel.
My car idles rough when started, rpm goes to 3000 and then starts to come down and is also giving poor mileage.
I had an exhaust leak earlier which I have fixed a month ago by taking to a mechanic who welded the leak and have also changed two flex pipes. The two codes P1273 & P1800 which were showing before were erased and didn't come back.
Today I opened the hood and I saw a loose pipe, pic attached. could this be the cause of the problem.
Thanks in advance.
