So this all started immediately after I had a clutch install. I picked up the car and threw a 0300 0315 and 0316 on there lot. They found that the crank sensor wire needed to be re wired and redo a crank relearn. I don't believe they changed the sensor 1 week ago. Then 4 days later I got these again 0300 0315 0316 and 0420 0430 (which I had those 2 420/430 when my lth were put on but the tuner turned it off). I cleared the codes as it started, idled and drove great all the way to the shop as I was getting a new belt put on. They said code never popped again and I picked up the car 24 hours later no code. Drove it all day no issues. Then this am the 0300 0316 0420 and p430 came back again car was all normal, cleared it and drove it all day....nothing back yet. I'm going to start a data log each morning and send to my tuner if it pops up again. It was 40°c both times these codes came up in the am . Plugs and injectors are all new less than 3 weeks. Any ideas?

Have you done a crank relearn?
They did... when they 1st tried I was next to him when he plugged in and revved it to 4500 and it cleared. He turned the car off and back on and it came back. That's when they said well I guess the car isn't ready. They called me about 1.5 hours later and said the wiring for the crank sensor needed fixed so they did that and everything was good for about 3 days and then the codes came back with the crank relearn in the mix but after I cleared it they had the car forr 24 hours just to see if the codes come back and they didn't. The. 2 days later they came back but no crank code just the 300/316/420/430.
