Honda Accord, Won’t Move Until I Hit the Gas Hard

“I am posting this here for Jason.”

I gave my car (Honda Accord) for repair yesterday as there was something wrong with the starter and the car would not start. They fixed that for me today. But I have a new problem now. I notice that as soon as I shift the gears from PARK to DRIVE4 (D4), the car would not move on it’s own and I would have to hit the gas pedal a great deal before it starts moving. This was not the case before.

Also, if this is relevant at all, the light that indicates D4 keeps blinking whether the car is on drive, park or reverse mode. This again was not the case until yesterday.

Also, the car stereo which was working until yesterday, is not working now.

The car service guys say it’s nothing that they have done and could not troubleshoot it. But the coincidence with all these happenings cause me to think otherwise. Unfortunately, my knowledge with cars is extremely poor and I humbly seek help from all you knowledgeable people out there. Any input would be highly appreciated. Hoping for the best.
Thanks,
Jason
