How do I get my money back it did not work

I once submitted all the required paperwork for the money back and they never sent me a dime. I did see slight lowering of some numbers but very little. Basically buy it but don’t expect to actually get a refund much less twice the amount

Does this clean oxygen sensors and catalytic converter?

This product cleans out just about everything totally from the gas tank to the exhaust tailpipe. Severely clogged systems may require a second treatment but anyone that lets it get to that point is probably going to need a lot more than an oil change and a few spark plugs.

Does it have to be done right before the test or a week before is okay?

i've done it 4 days before testing...and this is if you're failing due to a worn out cat converter; if you're not passing due to HC, that is a tune up and maybe new O2 sensor...

Will this help with the egg smell I get once in a while after I floor it. Doesn't stink all the time only once in a while

Yes, it will. The "rotten egg" smell is unburned fuel passing through your car due to dirty injectors, dirty intake valves, dirty compression chambers, dirty catalytic converts and dirty EGR valve & passageways, and dirty spark plug tips. This product cleans all of these areas.
