Q: Replaced spider injector and now it idled high and shifts into gear hard with a check engine light on

asked by on April 27, 2017

I had my spider injector replaced today and I got it back. I turned it on and it was idling high and figured the car needs to relearn the idle. About a mile down the road check engine light comes on and going from driving gears to neutral or park is a very hard shift. Any ideas of what might be going on

My car has 130000 miles.
My car has an automatic transmission.
