MaccyD Posted March 24, 2008 Share Posted March 24, 2008 In a bit of a mix up it seems the decat i bought has an unexpected sized hole where the cat temp sensor goes so it seems im going to have to run without one. Will it effect my fuel economy to not have it on there and if it doesnt can i do something to disable the cat temp warning light from coming on?Any input apreciated, thanks.

BenV Posted March 24, 2008 Share Posted March 24, 2008 i think thats the oxygen sensor and im prity sure its not good to run your car without one.your car will run like a pig because the mixture will be wrong. im not a 100% so id wait for some one with a little bit more knowledge.

StarletRick Posted March 24, 2008 Share Posted March 24, 2008 the top sensor is the lambda (O2), you need that or it will run really pants. the lower one is the cat temp sensor. and you can run without it, most decats dont have these anyway. Quote Link to post Share on other sites
MaccyD Posted March 24, 2008 Author Share Posted March 24, 2008 cheers rick, i was hoping that was the case. now i need to find a bung for the decat. and a vice to bend the bracing into the correct position. Quote Link to post Share on other sites

MaccyD Posted March 24, 2008 Author Share Posted March 24, 2008 cant speak for a glanza cat, but gt's have lambda at the top and a cat temp sensor poking out very close to the bottom. Quote Link to post Share on other sites
Glanza_Ragger Posted March 26, 2008 Share Posted March 26, 2008 cant speak for a glanza cat, but gt's have lambda at the top and a cat temp sensor poking out very close to the bottom.There identical Retain the top o2 sensor, ditch the lower cat temp as Rick said.You probably got a bung to screw into the lower sensor boss?
