A couple years ago my check engine light turned on and I got a diagnostic test on it. The code that came up was regarding the air injection system. The check engine light came on a couple times after that and it would turn off. I went back to the dealership a couple months after to get it serviced for that and they said because my check engine light isn't on right now, to not worry about it and they cant get any information if my check engine light isn't on. My car has been running fine and the check engine light hasn't come on since.
For the past couple days, Ive been feeling my car has been working hard to get up to speed. So this afternoon I was finishing up my errands and after my last stop, I started up my car and put it in reverse and my car jerked. When I put it in drive, it jerked even harder. I accelerated slowly just to see what would happen and it continued to jerk for about a mile or so. I checked my check engine light and it wasn't even on. So I checked the coolant temp and it was running a little high (average is 189-195f and high is 200-220f). It got up to 217. The only way it gets that high I noticed is when I'm going up a steep hill. But I wasn't on or near any steep hill. So I pulled over, turned off my car for a couple minutes and turned it back on and put it back in drive without it jerking. I drove a few feet and the jerking had stopped. The temp started to go back to normal to about 185-190f.
I was wondering if there was any suggestions as to what caused this? Does this relate to the air injection system? If so how much would it cost to repair or just for parts? Could it be my transmission? Is there any kind of special service I need if its my transmission? It kinda felt like my transmission was slipping just because it had to do with my gears shifting. My cars an automatic and its front wheel drive.
