messed with spark at idle closed and have it around 16 and sounds good most the time i cant wait to get my wide band and play with fueling at idle it smells really rich and add to that its getting cold have not messed with it really about to start again also took out the cats. changed the oil and all looks good getting it tested
Your narrow bands will tell you if its rich or lean.
Are your fuel trims reading crazy?
not really looked but i will check it out can you explain what i need to watch sorry its been so long hope u guys are still around
Just datalog Long Term Fuel Trims and Short Term Fuel trims.
Get it up to temp and just watch the trims. If they are constantly in the negatives more than 5% then it needs less fuel. If its in the Positives more than 5% then it needs fuel removed.
Think of your factory oxygen sensors to be more accurate at part throttle than Wideband. And Wideband only when in PE.
