Evening all,
This is my first post here so please be gentle =P I've recently brought an ST202 and today it went for its mot, apart from the various braking issues it failed on engine emissions. I know the car has been sat for a year or so and it did have some old fuel in it so I'm hoping that a fresh tank and some Wynns fuel treatment will do the job however the natural idle speed was lower than the limits, is there anything I can do to bump up the idle a fraction? Also is there anything else folk would suggest to get it through? Emissions sheet attached FYI.

Yea, takes more than a couple miles to get the cat up and running at peak efficiency. Hold a fast idle (2500 RPM) for about 5 minutes before taking the test when you're there. That WILL get the cat all heated up and ready to go. You can add denatured alcohol to the fuel to lower CO as well if you're just barely not passing on that.
