The only real way is to take it to a garage and get them to check the exhaust emissions. This only takes about 5 minutes and my local garage didn't charge me for this when I did this.

If the emissions are NOT OK, then this could point to problems with the fuel injection system as well. If the emissions are fine, then so is everything else.
