Thanks for the advice on the air flow meter. Since my last update (tired of them yet?), I have cleaned the O2 sensor and the air flow meter with STP Throttle Body & Intake Clearer and the car has been running fine no misses or hesitation while cruising or when the car is given full throttle. Hopefully, this has cured the sick car. I figured that if the air flow meter were bad the STP cleaner would not do any harm and was worth a try since I was unable to locate one locally to test.Your advice and patience is very much appreciated.
