I recently bought the car with 108000 miles. The owner put a new engine. Car sat for a year or so. Ive been driving it for a few days now. it started giving me trouble when I'd let it idel. It stalled and would not start. Went to work started rt up. Drove home about 20 min later it stalled at a light after trying to start several times it fired up and drove home fine. Got home let it ideal stalled again. Check engine light came on for code po372 also tac stopped working. So I changed out the opti. Car started great seemed good till I shut it off. And it would not restart id have to hold full throttle to get the car to fire after several attempts it again started and ran fine but stalled after 20 mins and would not start so now im stuck and don't know what to do please help. This is my 2nd camaro 30th anniversery edition and Im just frustrated
