Hello everyone,
My 2005 1.4 8V Dynamic Grande Punto only just passed its emissions test. This was on a retest, so I did the obvious things like replacing the spark plugs (old ones were oily!), changing the oil and filter (old oil was black) and air filter (dirty but not terrible). I also found that one of the breather hoses (from the back of the engine, I presume the crankcase breather) was disconnected so I reconnected that (top of the engine around the throttle was very oily, I presume from this).
Despite all this the technician had to rev the engine hard for about 10 minutes to get the emissions to get below the required amount.
So, I expect that it will fail again next time if I don't do something to fix it. Any suggestions?
Any other suggestions?
Cheers

- Engine "cleaner" that I put in the fuel tank - does anyone have any experience of this actually working, or is it just a placebo to use alongside other measures?
- Cleaning out the oil breather tubes from the cam cover and the crankcase - if they're blocked, will this improve emissions?
- Replacing the catalytic converter? A pretty expensive option that might not be the cause!
- Driving in 3rd gear at the speed limit on the motorway for one junction on the motorway and getting to the testing station as quickly as possible so the engine is still super-hot for the emissions test?!
Any other suggestions?
Cheers
