Check engine light came on while driving

Check engine light came on while driving. I got a list of problems but I'm still not sure. Couldn't be o2 sensors because it doesn't run up my gas and then when I go up a hill it doesn't affect the car so it's not the catalytic con. But I noticed something weird… When i put my leg to muffler it's not smooth how it used to be? It's like puffs in a way…. Oh and I do have to get a gasket for motor (oil) that's about it. Thank you.
My car has an automatic transmission.

help??

I bought this car from a personal owner, she told me that it had minor issues with the front motor mount being replaced and the cam shaft sensor the day I drove it the engine shut off in the middle of the road ,I had to switch gears to get it back running so I had asked and she said it had something to do with the problems I stated ,but today when I tried to start the car up ,It tried to crank but it wasn't successful and it said that the battery had died and "check the engine soon" light was on and of course that could mean a lot but if someone could please give me some answers

– help??

How long does it take to replace the lower radiator hose on this car? Do you think that $360 is an appropriate amount for the labor to replace…

I was recently quoted $530 to replace the lower radiator hose on my 2012 VW GTI. I found the part for sale on Pelican Parts for $110 and a gallon of coolant for $20. Even if the garage has a 30% mark-up on the parts, we should still only be talking about approximately $170 for parts. Do you think that $360 is an appropriate amount for the labor to replace this hose?

Thank you!!

1986 Chevy s10 with 171000 miles. Automatic with manual 4wd. Knocking/grinding noise when driving, any speed, worse when going straight.

I bought this truck for next to nothing as a project truck. I planned to fix the body because mechanically, it seemed fine. I started it this morning and started driving and hear a metal on metal grinding or dragging noise coming from around the driver front tire. Nothing is visibly broken or dragging. I don't see any fluid around the wheel. The noise is there when going straight or turning. It was loud and violent enough of a sound for me to turn around and park it. I'm looking for any advice because I've checked all I could at the time. I was unable to jack it up to inspect it be
