miko_supra Posted June 25, 2008 Share Posted June 25, 2008 yeah two o2 sensors and one cat temp sensor (you get a warning light on the dash if a temp limit is exceeded) Quote Link to comment Share on other sites More sharing options...

Jay_vr6 Posted June 26, 2008 Share Posted June 26, 2008 I have a stainless manifold and I removed the temp sensor as it had no where to fit on the new manifold. Makes no diff on the car running and no warning lights to say it isn't there. Quote Link to comment Share on other sites More sharing options...
Dan8 Posted June 26, 2008 Share Posted June 26, 2008 I did the same for my manifold and it seemed to use alot more petrol and when it got to 5400 rpm felt although it hit a wall in power or could it be a lamba sensor need replacing Quote Link to comment Share on other sites More sharing options...
Dan8 Posted June 26, 2008 Share Posted June 26, 2008 the manifold i bought only had a boss to fit just 1 lamba i got another boss fitted to the other side of the manifold as the stock in does and run it with both but the company i imported it from try to advise me to run it with 1 and to just solder another wire tapped into that sensor to run both sensor ports from 1 sensor i thought they where full of it and got another boss made but would it of been alright Quote Link to comment Share on other sites More sharing options...
Jay_vr6 Posted June 26, 2008 Share Posted June 26, 2008 hmm I got one of nics, I use both lambdas and its smooth as hell all the way through the rev range, but it does seem a little juicier on the petrol, although the way the price keeps going up its hard to tell.
