Hi Dan...sorry for the delay in replying, just got back last night from Fla, and while I was away I had the car worked on. The noise turned out to be the timing chain so had it and all the components replaced. Picked the car up tonight and it sounds sweet. Also had the idle control valve replaced, as well as the sub frame mounts and front shocks. Bottom line....I spent some money.
Anyway, hope all goes well for you as the top goes down and the smiles begin.

Regards,
George
