Here is a quick update for ya'll and didn't want to rush to judgement.....
I have to say for quite sometime now have been experiencing a rough idle,stumble situation especially in the colder months which honestly was quite frustrating to say the least and tried many troubleshooting methods to no avail!
I also noticed when returning to stock tune that my I/M took much longer than usual to complete especially the rear 02 sensors prior to inspection.
I guess a faulty purge valve is also known to throw off your fuel trims a bit which can cause the above mentioned symptoms,issues to occur.
Its also amazing that such a relatively cheap part can wreak mayhem in many ways.
I also wanted to give SHOdded a

for advising me in the right direction and IMHO the car is purring like a kitten and smoooooth as butter and back in business.
