Sounds like you may have some foreign body in the A/C system, what are the high and low pressures at idle.

What does that mean? And no I haven't got any way to check that ,no ac hookups but could u disrobe the term foreign body ?

Foreign body is something that does not belong where it is, as in your case you may have dislodged something when you replace the orface tube or accumulator tank,the moisture absorbing bags have been known to come apart that are housed in the accumulator and spread through the system. Was the system flushed before you started repairs?

No it wasn't..

These fragments could of came from the orface tube breaking I tryed to remove all but just maybe some slipped back down ac line...

Possibility very high that happened, you most likely will have to open the system back up and back-flush it. Take out the new tank and tube assembly and the lines from the compressor before flushing. might be a good idea to get some flushing compound from a parts store so you get all of it. then refill the system with oil and 134.

I was afraid of that .well thanks hopefully I can get to it next paycheck

How can I flush the system at home

You need an air compressor on that can make at least 50 lbs, and an A/C flush kit from your local parts store. Not too difficult once you get the system opened up enough. The hard part is pulling enough vacuum to get all of the moisture out of the system, it needs to be able to hold at least 28 inches of vacuum before you put anything back in the system.
