Only if it’s not too much trouble is correct.

 

[kadioguy]

Only if it’s not too much trouble is correct.

But when I google on the Internet, there are 923,000 results about "if it’s not too much of a trouble". It seems that the expression is very common.

Remember that the Web is populated by millions upon millions of non-native English speakers writing in English.

 

[kadioguy]

And the English written by many native speakers is of very dubious quality.

Thank you all!

But how can I find reliable sources?
Maybe Corpus of Contemporary American English or Google Books Ngram Viewer?
