I want you to know I appreciate your help and advice. The car does NOT seem to lag, seems to run fine. The mechanic tells me he took the top off the engine a second time, checked the belt timing, assures me it is correct. He says that BOTH cam sensors are plugged in as well. He said the only way to test the sensors is a resistance check, and they both check-out ok.
I really don't know what else that I can suggest to him. His thought was that one of the sensors may be going bad, and that "all you can do is wait and see if one of them fails at some point".
Any other thoughts, opinions and suggestions are welcome.
