So 5 months ago i had to change my crankshaft and camshaft position sensors because car went limp and threw those codes i replaced them all to still have a limp mode problem come to find out the tab on the crankshaft sensor was broken and the connecter was not clicking in so east fix i went to junkyard spliced a crankshaft sensor wire from a infiniti fx35 2010 same wire colors and had my mechanic splice it on he did a pretty good connection the only thing he forgot was the heat wrapping tape he just used electrical tape after that car running smooth for about 3 months then one morning today went to the gas station and tried to leave and the car is in limp mode doing the same effects as it did when i was going limp after i fixed the sensors and the tab was broke,No codes Should i check this connection?
