I have the car listed above 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, and my car threw the engine safety shut off switch 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. What should I do and what do you recommended? And should I try a fuel system cleaner?
