I drive 100+ miles (Highway) a day for work. Purchased Sept. 2019. My manual says at 75k miles. I am feeling hesitation a lot with gas pedal. I had a code for the air sensor, cleaned the air sensor with proper cleaner. I reset code. I have that hesitation and when in idol I can hear and feel engine idol change but not enough to see on tach. Any suggestions??????


suggestion's???

Well, it could be a few different issues. I would start by doing the simple cheap stuff first. Change the spark plugs. At the same time inspect the coil pack, and spark plug springs. Use some Techron fuel system cleaner ( or anything with PEA in it), this stuff actually works.
A simple easy way to check the MAF is by unplugging it. If it runs better unplugged, you need a new one.

This probably isn't causing you a problem now, but its a huge tune up item. Have the transmission fluid changed. I suggest doing two drain and fills, no flushing.
