I have a 2011 Ford Taurus SEL. A few weeks ago, a squirrel chewed some of the wires connected to my mass air flow sensor. So I got that fixed by a local shop. About a week later I drove close to 100 miles and after turning the car off at my destination, and got done, I got back in and started up the car, my car threw the check engine light and the oil light within seconds of start up, and my car threw the engine safety killswitch on. After a tow back to my hometown, Mechanic read code and diagnosed it as the oil pressure switch, so that was replaced. I also had the oil and filter changed at that time since I was close to due for it. Since then my car doesn’t seem to operate quite as smoothly as it should be or accelerate quite as easily (difference isn’t huge but seems a little noticeable). Also had one repeat of the check engine and oil light which a restart after a few minutes cleared it. But I am still having periodic hesitation and mild jerking upon accelerating from a stop (not every time just one here and there) AFTER the car has been driven for a while and everything is warm, even though it’s been cold here. It hesitated and jerked a little while making one of my turns today. What should I do and what do you recommended? It has about 94,500 miles on it currently.

May check to see if the critter(s) chewed some other undiscovered wiring. At 94,500 mi., you're close to being due for spark plugs if they haven't been swapped.

They haven’t been swapped out yet but it’s in the plans. I’m just trying to make sure there’s nothing more pressing first.

any updates op? when it comes to a jerking vehicle i like to make sure it gets inspected as soon as possible. i second about the spark plugs. its also definitely possible some other wiring was messed up and that needs to be taken into consideration as well.

Update: had some things cleaned, seemed to run smoother but still having issues. The other night we stalled out on the way home. After doing some research, we’re thinking it’s possibly the camshaft position sensor. RPM was all over the place as we experienced both hesitation and even a surge.
check engine light and oil indicator (on the screen below the speedometer) came on. My Bluetooth code reader wasn’t picking up any codes from that. Currently having everything checked out by a local shop, so we’ll see how it goes.
If anyone else has any suggestions, I’m open and can run those by the mechanic.

CMP loss of sync will set a code and turn on the CEL.

If your Blue tooth reader is not picking up codes with a light on, I would try a different code reader.

^^^^^ Good call. Some cheaper code readers will not read manufacturer specific codes. Manufacturer specific codes are VERY common on all makes / models of newer vehicles.
