Just put in 224 cam. Fired up the car tonite for first time and tach started acting funny. It worked fine for a while. The car wouldnt hold an idle, so I kept having to restart it. After restarting it several times the tach started not working. I would start the car and it would be dead for prob the first 45 sec to a min of car running then it would all of the sudden jump up. I dont know where tach gets it signal if I may have bumped some wires during the cam swap, I know I was a little rough on the crank position sensor when I was breaking the convertor bolts loose.......

I am not throwing any ses lights though....
