There was no waiting for Richard to arrive as he came about 20 minutes early. Had all the necessary tools to do the job. He performed the changing of the crankshaft position sensor in less then the time alotted (which I just knew couldn't be done). Access to this component is fairly restricted. I know this because I attempted to change this myself. I'm very,very pleased with the work Richard performed and WILL have him back to do other work on my car........Thank you, Richard for a job well done.
