ok i got my car put all back together with the motor i bought for $350 i got it on the road and after a day when i puled out infront of somebody i found out that it wount rev over 4000 rpm's is this becase its not completly reprogramed or could it be more. it wont do it in park nutral or even drive so when im on the highway i cant go to passing gear....... please help me

 

i ran my codes and one was that the map sensor has no voltage or signal could this have something to do with it

 

i replaced my map sensor today and now i can go over 4000 rpm. turnes out the car was in limp mode. it also turnes out that my new motor has bigger b@ll$ than my outher 1. unfortanitly my car idles ruff now and when i slow down sometimes my car will stall out and then start back up agian (sometimes it dousnt even do that) i figger that this is becase my car relerned how to idle without the map sensor. is there any way that i can set the car to relean again without leving it unpluged for a few days or how long doues it need to be unpluged. or will it just eventaly relearn without compleatly going though the whole proses.
please help.... i know you dont have to be ASE certified to know this but i am lost
