alaing Posted May 25, 2009 Share Posted May 25, 2009 Thought id post this here as well as mr2oc. Car went in for its mot this week and failed on emissions, the reading was 7.5% !!!! When it should be down at 3.5%. Shes a rev2 tubby with the cat still in place and no other modifications. What could make these readings so high?! I have recently replaced the TPS sensor as i had idle issues but seem to have solved that now. Any input would be a BIG help Oh, no fault codes or anything else. Thanks in advance Alain Quote Link to comment Share on other sites More sharing options...
