Matt1878 Posted August 8, 2015 Share Posted August 8, 2015 Cat issue probably Quote Link to post Share on other sites
StuDoc 72 Posted August 10, 2015 Share Posted August 10, 2015 It failed because the guy is a knob end and actually tested it. Tell him to get a yaris thrown through or your gonna knock him on his sweaty hole. Quote Link to post Share on other sites
sophiealice Posted August 10, 2015 Author Share Posted August 10, 2015 Checked the cat and all seems ok so not too sure what else it could be ' it failed on the 2nd fast idle test it was 0.61 on carbon monoxide or something anyone else suggest other reason it could be thanks ?

StuDoc 72 Posted August 10, 2015 Share Posted August 10, 2015 What mods you got? Quote Link to post Share on other sites
sophiealice Posted August 10, 2015 Author Share Posted August 10, 2015 Only mod on the car is cobra exhaust system and a air filter that's literally it not really done mods to it yet. Quote Link to post Share on other sites
JayJ Posted August 10, 2015 Share Posted August 10, 2015 High CO means that you are running rich mixture. Common faults are lambda, cat, bad plugs/plug leads/distributor cap/rotor. Also the engine temp sensor might be the problem, but usually you got CEL then. Quote Link to post Share on other sites
sophiealice Posted August 10, 2015 Author Share Posted August 10, 2015 I'll check the lambda and cat again carnt see it been plugs there new and the new leads and distributor cap and rota is new as I had missfire early this year I will also check the engine temp sesnor thank you 😁 Quote Link to post Share on other sites
Paton Posted August 10, 2015 Share Posted August 10, 2015 You can get CAT cleaners to help pass the MOT, might be worth a try. Did it one year on mine at a garage when it failed then passed. Quote Link to post Share on other sites
sophiealice Posted August 10, 2015 Author Share Posted August 10, 2015 I'll give the cat cleaner ago thank you 😁 Quote Link to post Share on other sites
Jhandy Posted August 11, 2015 Share Posted August 11, 2015 lambdas are a servicable item on these cars, and also, give the car a good fast high rev drive before the test, as the cat will only work correctly at high temps Quote Link to post Share on other sites
