daniel_g Posted September 12, 2017 Share Posted September 12, 2017 Pretty strict for an old car.High CO is excessive carbon monoxide reading so unburnt / rich fuel mixture.Turn the FPR down if you can, take the air filter off.Failing that slip the tester a few quid.

federalman Posted October 23, 2017 Share Posted October 23, 2017 If you're still running the original and I would assume it is judging by it being the stock one I'd suggest changing the fuel pressure regulator. Failing that I'd take a look at the injectors. Quote Link to post Share on other sites
