Hi Scotty,

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.

Clean the MAF sensor, replace air filter and also clean the idle air control valve.
