Got an engine replacement and new fuel pump the car went into limp mode after driving for about 30 min. While cleaning the maf sensors and throttle bodies I found that the ground wasn’t plugged in. I drove the car for a little over 2 weeks no problem then the car wouldnt move at a red light doing what you see in the video. I managed to get it into a parking lot. I come back 2 hours later and the car drove 9 miles home like nothing ever happened. What do you think the problem may be and what can I check.
