Sorry if this question is asked thousands of times.
I will make it as simple as possible.
I have 99 Civic EX and it has done 95K.
I purchased it from a lady who wasn't sure about timing belt was
changed .she said she got some belts changed. She didn't know much
about the CAR and service. I got it checked before buying and the
mechanic told me that he cannot check the state of TB. There is a lot
of work involved. My questions:

1) Can I get it(TB) checked? If yes then how much it would cost me? I
guess a lot.
2) What is the cost involved in changing of TB (without pumps and with
pumps) and other things which usually go with TB change?
3) I am in east coast near DC. Any suggestions who should be the best
for this job. I know dealers are good but the expenses at their shops
are very high.

Your help will be highly appreciated.

Thanks.
